Dev/mip 507/support for smpc operations
Created by: ThanKarab
Changelog:
- Support for sum/min/max operations in SMPC's secure_transfer. Jira
- Supported types are both int/float.
- 'type' is no longer needed in the secure_transfer object. SMPC cluster should handle both types.
- Bug fix in controller when multiple SMPC computations are needed.
- Refactored 'smpc_standard_deviation' test algorithm to return column's min/max values.
