NC | CLI | Lifecycle worker

[romayalon]

Explain the changes

This PR adds the NC CLI command used for running the lifecycle worker.

1. Added a new CLI command type called lifecycle and options that currently contain only the global options.
2. Started creating a frame for the nc_lifecycle worker process -

• Block noobaa nc_lifecycle worker from working if NooBaa service is not running.
• list buckets, iterate them and on every bucket that contains a lifecycle policy - handle the rules.
• handle_bucket_rule logic -
  • check that the rule is enabled
  • get delete candidates
  • call delete multiple objects
  • update last_sync of the processed lifecycle rule
• the actual rules processing will be added in the next PRs, currently its implementation is empty.

3. Added 2 new manage_nsfs_cli errors - SystemJsonIsMissing and NooBaaServiceIsNotActive.

Refactoring -

1. moved nsfsObjectSDK from nsfs.js to its own file src/sdk/nsfs_object_sdk.js and updated its callers.
2. moved NOOBAA_SERVICE_NAME and service state status check by systectl call from health.js to manage_nsfs_cli_utils.js.

Issues: Fixed #xxx / Gap #xxx

Gaps -

1. Add implementation of the processing of the 4 rules in POSIX.
2. Add implementation of the processing of expiration and nonCurrenytays
3. Add notifications usage.
4. Decide on batch size
5. Endpoints Stats should be supported? currently we will not collect stats on the lifecycle worker process.
6. Add CLI unit tests
7. Add CLI documentation.
