port test_server_metadata and test_server_personality into v3 part1

This changeset only copies the v2 files into the appropriate v3
directories unchanged. This is being tried in order to make
reviewing of the porting easier as gerrit will display only what
is actually changed for v3 rather than entirely new files.

Partially implements blueprint nova-v3-api-tests

Rip out the coverage extension client from tempest

remove the test: test_service_enable_disable

this removes the test: test_service_enable_disable, due to race

Move import to import block again

Since tempest.stress.driver doesn't use the admin manager in a static
variable anylonger we can move the import back to the block.
