** Description changed:
Retry https://paste.opendev.org/show/bCtEYsFr0oTfhY9b2r34/
so that a connection error to neutron (maybe due to kubernetes
maintenance) does not immediately lead to share create failure. May be
retry for 5 times with keystone connection failure to avoid duplicate
port create in neutron. If duplicate ports are created, they become
orphan after share deletion. So Manila should give a try to make sure
duplicate ports are not created.

[Impact]
- This is an improvement very desired to be included in SRU of LP#2074504.
- We have not personally encountered this issue because it is very rare
- but it is a potential problem that was adressed prior to fixing
- LP#2074504 and further enhances LP#2074504's fix.
+ Temporary connectivity issues will cause immediate failures in share creation.

[Test case]
Given the nature of this bug, we cannot replicate this in the lab. Unit
tests plus upstream CI validation that this works and doesn't break
anything should suffice.
[Where problems could occur]
The code only affects the neutron plugin for manila, which is used only
for DHSS=True mode. In case something breaks, it will fail to create new
resources such as share servers and share networks. Existing resources
should be fine and new shares should still be created fine in existing
share servers and share networks. In case of a regression, the previous
funcionality can be restored through package downgrade.
[Other Info]
This is only for Jammy/Yoga as part of SRU LP#2074504.
