Add PbmCheckCompatibility method in pbm simulator code similar to PbmCheckRequirements.
This simulator function is getting called from the vSphere CSI plugin unit tests. Without this function following error is observed.

How Has This Been Tested?

Unit tests in vSphere CSI plugin using Storage Policy were using workaround till now, so PbmCheckCompatibility function in simulator was not getting called. But to test the relevant code in CSI, we are planning to remove this workaround. So, we need to implement simulated function PbmCheckCompatibility.
After locally adding this code, unit tests are passing in CSI plugin.

• Test Description 1
  1. Create new Storage Policy using pbm
  2. Pass newly created storage policy name to CreateVolume call through parameters
  3. Make sure that volume creation is successful and volume is using the correct storage policy.
• Test Description 2
