Error when executing action with field relying on keyring

[davidferlay]

Observed

• Error is thrown when executing an action which uses keyring.GetKeyValue processor
  • if related field is not manually filled in UI
  • if keyring passphrase value / path is not passed to command launching webui

Expected

• Would be great to handle more gracefully that use case:
  • either with a more explainatory message like Please launch webui with keyrring option or set value for fields relying on keyring
  • or have ability to set keyring passphrase value or path (as global options) Ability to use global flags when executing actions from UI #116
  • or both
  • or something else
