[1.5] No keyring error with --export

[heitorPB]

Hello,

I am trying to export a limited auth token to use with Github actions, but I had no success so far:

$ CHARMCRAFT_AUTH="" charmcraft login --export=gh.auth --charm slurmd --charm slurmdbd --charm slurmctld --charm slurmrestd --permission package-manage
No keyring found to store or retrieve credentials from.

I am using Ubuntu LTS server 20.04, headless. Charmcraft from latest/candidate (version 1.5.0, rev 834).

I thougth the --export flag would cause Charmcraft to not use a keyring?

This is indeed not the case today, I will discuss with @facundobatista

[heitorPB]

This is similar to #719, but not exactly a duplicate?

[facundobatista]

@sergiusens it looks like Craft Store is always expecting a keyring to be available when not having a CHARMCRAFT_AUTH set (and of course will not allow to use the login command when having that environment variable).

[sergiusens]

@facundobatista correct, this is what you asked for, you wanted login to always login and potentially show the credentials.
I brought it up, we need a new key to say that we don't want to record this, either by not passing in the environment variable on init or the ephemeral argument I proposed.

Fixed by #760.
