+1, you do not want a monolithic plugin that does everything. Creating a
separate small plugin to install ovs from source and the other pieces necessary
for doing that is the best path for enabling this.

This is the intended way to use plugins. Dumping everything but the kitchen
sink into a single plugin is just going to tightly couple too much and lead
to an undebugable tangled ball of yarn. The idea with plugins is to have
smaller plugins that can be used in conjunction to configure and enable
various additional pieces.

I don't think you ever want to have a gating job with OVS from source.
There is way too much potential instability when building something like this
from source to rely on it. An experimental job would probably be as far as I
would go with something like this. Going any further than that is just asking
