Add support to recover workload data (in place)

[hossainemruz]

Tasks:

• Update recovery command & process to check recoveryPolicy
• Update Recovery controller to support in-place recovery.
• On reconciliation, it will determine weather to recover through init-container or Job and perform following tasks:
  • if recovery mode is init-container then, inject a init-container and restart workload (scale-down-to-zero, scale-up-to-one, scale-up-to-original-replica)
  • if recovery mode is job then do nothing ( we will address in later issues).
