NC | Lifecycle | Health

[romayalon]

Describe the Problem

The NC health CLI should report on the latest lifecycle worker run.

Explain the Changes

1. health.js - Added get_lifecycle_health_status() and get_latest_lifecycle_run_status() functions that return the status of the latest lifecycle run on the current host.
2. manage_nsfs_constants - added --lifecycle flag to health options
3. manage_nsfs_help_utils - added --lifecycle help.
4. test_nc_health.js - added unit tests

Issues: Fixed #xxx / Gap #xxx

1. Gap - Open question - do we need to trigger an event with Degraded/Healthy status?

Testing Instructions:

1. Auto -

sudo NC_CORETEST=true node ./node_modules/mocha/bin/mocha src/test/unit_tests/test_nc_health.js  --g "health - lifecycle"

2. Manual -
   a. Empty scenario - run noobaa-cli diagnose health --lifecycle
   b. valid scenario -
   b.1. run noobaa-cli lifecycle 3 times.
   b.2. run noobaa-cli diagnose health --lifecycle and expect to have the latest run information.
   c. error scenario =
   c.1. Edit config.json and set NC_LIFECYLE_TIMEOUT_MS to be 1.
   c.2. run noobaa-cli diagnose health --lifecycle and expect to have the latest run information including the timeout error.
