Boden R 410a83c89d use plugin common utils from neutron-lib
A bulk of the public APIs that are part of neutron.plugins.common.utils
were rehomed into neutron-lib with [1] and the remaining with [2].

This patch consumes [1] by:
- Removing the rehomed code from neutron.
- Removing the UTs that are no longer applicable.
- Leaving the functions in [2][3] in neutron.plugins.common.utils until
we release [2][3] and can consume it at which point we should be able to
remove the utils module.
