[Bug 2117135] [NEW] python-neutronclient generates excessive entries in ~/.cache/python-entrypoints when called often

[Ghadi Rahme]

Public bug reported:

Currently pyhton-neutronclient creates entry points when called due to
it trying to register extensions in the init of the Client class
(neutronclient/v2_0/client.py).

Some applications such as octavia make use of python-neutronclient and
in the Octavia charm, this class is being initialized on each update
status hook run leading to an excessive amount of entries in
~/.cache/python-entrypoints.

In the case of Octavia, nothing is needed beyond the built-in feature
set of python-neutronclient based on my testing. From what I can tell
Octavia uses the API to fetch the MTU of other machines. Adding an
option to decide if an application wants python-neutronclient to
register more extensions would avoid this issue.
