COPR deploy

[Michal Novotny]

Hello, we have just deployed copr-frontend 1.117 and copr-dist-git 0.34.
The deploy is quite special because the packages' origin is Fedora
Infrastructure repositories for the first time and not @copr/copr repo as
it used to be. That is because we have switched to deploying COPR only from
official Fedora repositories (and from the dedicated Infrastructure
repositories for hotfixing) to be able to get Fedora Infrastructure support.

Apart from that, those two packages fix several bugs:

- *Bug 1473671* <https://bugzilla.redhat.com/show_bug.cgi?id=1473671> - Could
not parse /tmp/tmpGj3KZs/rust-bytecount.spec with error can't parse specfile
- *Bug 1473361* <https://bugzilla.redhat.com/show_bug.cgi?id=1473361> - New
SCM 2 build does not recall the 'Subdirectory' setting
- DistGitProvider has been reimplemented
- *Bug 1460399* <https://bugzilla.redhat.com/show_bug.cgi?id=1460399> - Build
breadcrumb incorrect for group project (yet to be closed)
- sqlalchemy deprecation warnings fixed
- monitor page fixed from jinja 2.9
- #106 <https://pagure.io/copr/copr/issue/106> Renaming a spec file in a
newer version causes the build to fail

And also SELinux was set to Enforcing on copr-dist-git machine...

We have also updated docs with respect to the SCM source type
https://docs.pagure.org/copr.copr/user_documentation.html#scm. There is one
bit missing and that is that copr-cli buildmock currently stands for SCM-2
and copr-cli buildtito currently stands for SCM-1.

Enjoy
COPR team
