[Pulp-dev] Pulp 2 and 3 Service Name Clashes

As I understand the discussion on 4497, it was to be hyphens *in addition
to* a name change, but you're right @ehelms that I only see the hyphen

I'm +1 on @rchan's suggestion that the change take place in pulp2.

Also given the migration and complexities with support, I agree with
@ehelms that custom configuration of these names would be problematic, so
I'm -0 on this unless we have a compelling user story for needing the
customizability (assuming we are making the change to the service names in
pulp2 ourselves).
