Cache SecurityGroupAPI results from neutron multiplexer

Browse Source 
On a normal run of the multinode grenade job, the n-api service alone
creates nova.compute.api.SecurityGroupAPI object 183 times. This patch
caches the object after the first creation. Since there are two ways
one can instantiate that API, we cache each independently, dropping the
count from 183 to 2.
