Instead of setting up the routes inside a function we can now use a
BlueprintSkip class, which allows us to register them at different
routes (eg. /api/v0/ and /api/v1/) and override any routes that will be
replaced by the new API version.
When the kickstart is handed off to Anaconda for building it will
download its own copy of the metadata and re-run the depsolve. So if the
dnf cache isn't current there will be a mismatch and the build will
fail to find some of the versions in final-kickstart.ks
This adds a new context to DNFLock, .lock_check, that will force a check
of the metadata. It also implements its own timeout and forces a
refresh of the metadata when that expires because the dnf expiration
doesn't always work as expected.
Resolves: rhbz#1631561
Depsolve the packages included in the templates and report any errors
using the /api/status 'msgs' field. This should help narrow down
problems with package sources not being setup correctly.
