Maintain methods across redirects

[ikravets]

I've originally stumbled upon this issue after upgrading Gitlab server
from HTTP-only to HTTPS, but forgetting to update some scripts
which use gitlab cli. The cli behaved like everything is fine, but a
server has effectively become "read-only". I guess, I may be not the
only one bitten by this issue, so I've fixed it for everyone.

Citing the commit message:

If HTTPS is enabled on a server, but the client uses plain HTTP
Gitlab generates HTTP 301 redirect. By default HTTParty will
follow with GET request regardless of the original method and
any PUT/POST will silently fail to update the target. Fix by
enabling HTTParty::maintain_method_across_redirects.
