Automatically update personal GPG public keys

Once your personal GPG key has expired, all commits signed with this key turn "unverified", even though they had been shown as verified a minute ago.

When you want to update the expired public key in your profile, you have to delete the old one first and then re-add the same but renewed key again. Instead of complaining about the same already being there, the key should at least be overridable.

But actually, since you do not want to manually update your renewed public key on all the GitLab instances you have an account on, there should be options to have the key update automatically.

Since the PGP web of trust seems to cease away, there should not only be one keyserver, but a dedicated form field with a source to look at, per key. This should be able to read all sorts of keyservers like SKS, Hagrid, Keybase, etc. and not least WKD.
