Code Issues Proposed changes

Don't fatal error during initialization for missing service providers

Browse Source 
Sometime during the split, code was added to fixup driver paths,
which imports service providers even for plugins which are not
in use. That, combined with neutron including default service
providers for VPN and LOADBALANCER, resulted in a really messy
mess in terms of removing VPN from the main neutron test suites.

This change stops the imports, so that if one of the services is
missing, neutron server can still start. It likely breaks the driver
path fixup, which can be fixed outside of this gate blockage.
