Metro volume expand support

[aqu-dell]

Description

• When we expand one of the metro volumes, we want the other to expand as well in response. In these changes we, pause the replication session before we expand the local volume, and then resume after we expand the local volume. The remote volume should expand as a result.
• Note: We observed that NodeExpandVolume will continue to fail till the metro session is resumed and remote volume gets updated size.

How Has This Been Tested?

Tested expanding both regular and metro volume, and they succeeded.
Controller and node logs are attached to ticket 26867.

Can we add more tests coverage the negative scenarios to increase code coverage?
