Subject: [PATCH] dnf: Add support for coercing upgrade to distupgrade

Some distributions (particularly rolling release distributions)
prefer that normal "upgrade" actions actually trigger the distupgrade
method in the package manager. This change enables that if the
installed  distribution release package specifies that this
behavior must occur.
