This loads the system dnf vars from /etc/dnf/vars at startup if
system repos are enabled, and it substitutes the values in the sources
when loaded, and when a new source is added.
Also includes tests.
This changes the source 'name' field to match the DNF usage of it as a
descriptive string. 'id' is now used as the short name to refer to the
source. The v0 API remains unchanged.
Tests for v1 behavior have been added.
Now that the v1 API is in use the status message will return api: 1
DNF Repo.dump() function cannot be used as a .repo file for dnf due to
it writing baseurl and gpgkey as a list instead of a string. Add a new
function to write this in the correct format, and limited to the fields
we use.
Add a test for the new function.
Fix /projects/source/info to return an error 400 if a nonexistant TOML
source is requested. If JSON is used the error is part of the standard
response.
Update test_server.py to check for the correct error code.
