Fine granular policy management

[IDM.TSA.E1.00010] Fine granular policy management

The system SHOULD allow managing policies in separate GIT repositories. This will allow separate
GIT Workflows for different system contexts. Synchronization mechanisms SHOULD be separate
for different GIT repositories. A new URL path parameter SHOULD be introduced in order to
achieve context separation upon policy evaluation.

Example:
Current evaluation URL:
../policy/{group}/{name}/{version}/evaluation
Evaluation URL with GIT Repository separation:
../policy/{repository}/{group}/{name}/{version}/evaluation
