Fix usage of network clients among compute or neutron

[Ghanshyam Mann]

compute network client are 404 after 2.35 microversion so each test needs to use neutron client if requested microversion is >2.35 otherwise keep using compute client to keep the nova-network coverage for stable supported branches.

Above is being fixed as part of https://review.openstack.org/#/q/topic:bp/clear-deprecated-api+(status:open+OR+status:merged)

But few place, it has not been taken care correctly. neutron client is being used with out nova-network or microversion check [1] which break the cloud testing having nova network enabled.

What is the status?

[Ghanshyam Mann (ghanshyammann)]

This is not yet fixed, we need to be careful on not losing the coverage for stable branhes
