[Issue] OVS Source and types are different in OSP and remotehost endpoint

@atheurer @k-rister @mrbojangles3

During the remotehost endpoint, I noticed that ovs metrics types are different compared to osp(all-in-one) endpoint test scenario.

The remotehost endpoint should collect similar metrics as osp endpoint.

Ovs metrics types in remote host endpoint test:
