Because `MANILA_INSTALL_TEMPEST_PLUGIN_SYSTEMWIDE` defaults to true in
manila's devstack plugin [1], we're getting tempest plugin. This is
problematic for us because:
- we don't want to spend extra time installing unneeded dependencies
- this makes it more likely to break, as shown with #2440.

This commit sets `MANILA_INSTALL_TEMPEST_PLUGIN_SYSTEMWIDE` to false in
the Share Filesystems job.

Fixes #2440.

Do not install tempest in sharedfilesystems jobs

neutron-vpnaas recently removed stable/ussuri and stable/train branches.
We now need to use the ussuri-eol and train-eol tags instead when pulling
from the project.

Fixes #2447

Fix train and ussuri networking jobs

With go 1.19, automated go formatting with `go fmt` applies to comments
as well. This caused the unit test job to fail on new PRs. Let's apply
the go 1.19 formatting to the whole code base.

Fixes #2449
