Comment 1 for bug 1870910

Further analsyis shows that the message "vault relations's interface, secrets-storage, is related but has no units in the relation." is misleading and is being show as a result of charm-helpers.contrib.openstack.vaultlocker.VaultKVContext().complete being false due to the fact that the related vault charm has not provided a token. I assume this a race issue on the vault charm side since a token should have been provided when vault was unsealed.
