Comment 2 for bug 1915853

The problem is that the action method does not return immediately when setting status as failed when running on non-leader unit.

Additionally I see that also the problem happens for other action that relies on hookenv.leader_set like get-csr. So the patch will cover also these methods

$ juju run-action --wait vault/4 get-csr token=s.vRujzbfRgzf5fBtZKnY4HcCC ; juju debug-log
unit-vault-4:
  UnitId: vault/4
  id: "43"
  message: 'subprocess.CalledProcessError: Command ''[''leader-set'', ''root-ca='']''
    returned non-zero exit status 1.'
  results:
    Stderr: |
      ERROR cannot write leadership settings: cannot write settings: not the leader
  status: failed
