How to avoid re-generating Pagure API keys all the time?

[Pavel Raiskup]

From time to time I have to submit a ticket with 'fedpkg request-repo' or
'fedpkg request-branch', and I have feeling that I have to regenerate the API
key very often (since 2018-02-17 I have 5th key already?!).

How do you work-around this requirement to re-generate the key all the
time?  Is this necessary requirement for 'fedpkg' to work if when we have
gssapi support in Fedora?
