Configurable retry time or shorten time

[iBobik]

Build process can take some time, so challenge file can be invalid when published:

$ gitlab-le --token xxxxxx --path /acme-challenge --jekyll --email xx@xx.xx --production --repository https://gitlab.com/xxx/xxx --domain www.xxx.xx

Uploaded challenge file, polling until it is available at http://www.xxx.xx/.well-known/acme-challenge/xxx

TODO: modules which depend on this module should expose this error properly but since some of them don't, I expose it here directly:

We can not make GitLab CI run faster, but it is possible to decrease probability of fail by shortening retry time. It should not be problem to retry always after 30 seconds because that retry is free.

I'm also hit by this. I tried to remove the "double factor", but this didn't solve it neither:

For me removing double factor and disabling tests in CI solved it for me. And probably it helped to do it at night when GitLab's shared runners are idle. :-)

It seems final solution will be there: https://gitlab.com/gitlab-org/gitlab-ce/issues/28996
