Code Issues Proposed changes

Add --scheduler_hints to share create command 

This commit add --scheduler_hints option to share create command. Users
can specify affinity/anti-affinity share ids to share create command as
value in <key=value> pairs of scheduler hints. The possible keys are
same_host and different_host. Available from microversion 2.65.

Partially-implements: bp affinity-antiaffinity-filter

features:
- Added --scheduler_hints to the share create command
upgrade:
- Scheduler hints in the share create command allow scheduler to select
appropriate host using hard affinity and anti-affinity filters. User needs
to specify affinity/anti-affinity share ids using keys "same_host" or
"different_host" when creating a manila share.
