Comment 12 for bug 1735402

I've worked through this with Anastasia on IRC, the process to fix the situation we're in is:

1. juju add-credential azure
2. juju credentials azure --format yaml --show-secrets
3. Take the output of the above, paste it into azure-creds.yaml, update the values of appication-id and application-password for your old credential to match those of the one you just added.
4. juju add-credential azure -f azure-creds.yaml --replace
5. juju update-credential azure <name of your old creds>
