[FEATURE REQUEST] Backup OpenSearch in HA mode

[sk4zuzu]

Is your feature request related to a problem? Please describe. Backup feature does not work with clustered multi-node OpenSearch. Please check #884.

Describe the solution you'd like Backup code should work with clustered multi-node OpenSearch .

Describe alternatives you've considered N/A

Additional context Clustered multi-node OpenSearch requires shared folder (for example NFS) to create / restore snapshots. Epiphany does not support such a shared storage currently.
