[SVF] Fix rccg and relationship creation issues

Browse Source 
[Spectrum Virtualize Family] Fix issues while creating a mirror
volume and creating a group by using the storage backend system_id
in the place of system_name in create_relationship and create_rccg
calls to choose the correct partnership based on the system_id.

This issue occurs when multiple partnerships in different states
are available for the same storage system_name.

Closes-Bug: #1939145
