1. A system, comprising: a turbine engine comprising an exterior shell disposed about internal rotary components;a pedestal configured to support the turbine engine, wherein a first support is coupled to the pedestal and a second support is coupled to the exterior shell, and the first and second supports are located outside of the exterior shell; andan alignment key pack configured to mount between the first and second supports, wherein the key pack comprises a plurality of key segments selectively arranged one over another to define a thickness to adjust a position of the exterior shell relative to the pedestal for alignment of the exterior shell with the internal rotary components. 2. The system of claim 1, wherein the alignment key pack comprises a main key segment and a plurality of shim segments, the main key segment has a main key thickness that is insufficient to adjust the position of the exterior shell for alignment with the internal rotary components, and at least one of the plurality of shim segments is stacked with the main key segment to provide the thickness sufficient to adjust the position of the exterior shell for alignment with the internal rotary components. 3. The system of claim 1, wherein the turbine engine comprises a first turbine stage and a second turbine stage, the pedestal is disposed between the first and second turbine stages, and the thickness of the alignment key pack is variable based on a selection of the key segments to adjust to adjust the position of the exterior shell of the first turbine stage or the second turbine stage for alignment with the internal rotary components of the first turbine stage or the second turbine stage. 4. The system of claim 1, wherein the first support comprises a support block extending from a lower portion of the pedestal, the second support comprises an arm extending from the exterior shell of the turbine engine, and the alignment key pack is disposed vertically between the support block and the arm. 5. The system of claim 2, wherein each of the plurality of shim segments has a shim thickness of at least less than approximately 5 percent of the main key thickness of the main key segment. 6. The system of claim 2, wherein the first support comprises a support block having a recess disposed between opposite tabs, one or more shim segments of the plurality of shim segments are disposed in the recess between the opposite tabs, the main key segment extends over the one or more shim segments, and a lockable plate locks the main key segment to the first support. 7. The system of claim 1, wherein the key segments have different thicknesses from one another, and each of the key segments comprises a metal plate. 8. The system of claim 1, wherein the alignment key pack is configured to provide the thickness to adjust the position of the exterior shell in a vertical direction for alignment with the internal rotary components via selective stacking of the key segments without any machining. 9. The system of claim 1, wherein the turbine engine comprises a steam turbine engine. 10. A system, comprising: a turbine support key, comprising a set of key segments selectively stackable together in a plurality of combinations to adjust a thickness between turbine supports to adjust a position of an exterior turbine shell relative to a pedestal for alignment of the exterior turbine shell with internal rotary turbine components based solely on a selection of the key segments from the set. 11. The system of claim 10, wherein the wherein the set of key segments comprises a main key segment having a main key thickness that is insufficient to adjust the position of the exterior turbine shell for alignment with the internal rotary turbine components, and the set of key segments comprises at least one shim segment that is stackable with the main key segment to provide the thickness sufficient to adjust the position of the exterior turbine shell for alignment with the internal rotary turbine components. 12. The system of claim 10, comprising at least one of the turbine supports having a recess between opposite tabs configured to receive the turbine support key. 13. The system of claim 10, wherein the key segments comprise a plurality of shim segments disposed in a pocket of a main key segment, wherein a perimeter of the pocket surrounds an outer perimeter of the shim segments. 14. The system of claim 10, wherein the turbine support key is configured to support at least approximately 50,000 pounds, and the turbine support key comprises stellite. 15. The system of claim 10, wherein the key segments comprises a main key segment and a plurality of shim segments, the main key segment is less than or equal to approximately 1 inch thick, and the shim segments are less than or equal to approximately 20 mils thick. 16. The system of claim 10, wherein the key segments have different thicknesses from one another, and each of the key segments comprises a metal plate. 17. The system of claim 10, comprising the exterior turbine shell, wherein the thickness adjusts the position of an upper half of the exterior turbine shell and a lower half of the exterior turbine shell relative to the pedestal for alignment of the upper and lower halves of the exterior turbine shell with the internal rotary turbine components, and the upper and lower halves of the exterior shell remain in a fixed orientation relative to one another while the thickness adjusts the position. 18. The system of claim 17, comprising a steam turbine having the exterior turbine shell, the internal rotary turbine components, the turbine supports, and the turbine support key. 19. The system of claim 17, wherein the turbine supports comprise an arm of the upper half of the exterior turbine shell and a support block of the pedestal. 20. A system, comprising: a turbine pedestal having a first turbine support configured to support a second turbine support coupled to an exterior shell disposed about internal rotary components of a turbine; anda key pack having two or more key segments selectively stacked into a key stack to define a thickness to adjust a position of the exterior shell relative to the turbine pedestal for alignment of the exterior shell with the internal rotary components. 21. The system of claim 20, wherein the key pack comprises a main key segment and a plurality of shim segments, the main key segment has a main key thickness that is insufficient to adjust the position of the exterior shell for alignment with the internal rotary components, and at least one of the plurality of shim segments is stacked with the main key segment to provide the thickness sufficient to adjust the position of the exterior shell for alignment with the internal rotary components.
