Customer cloud likely needs Neutron 14.2.0 (bionic/stein)

[Paul Goins]

On a customer cloud, we were having issues regarding some OVS rules or routes not being created properly.

SEG suspected this was https://pad.lv/1794991, suggesting that we tweak the l2pop agent_boot_time setting from 180 to 1800.

The cloud, however, is running Stein, where the code generally seems to avoid using that setting in the general case in favor of a new methodology. (https://review.opendev.org/#/c/649729/8/neutron/plugins/ml2/drivers/l2pop/mech_driver.py seems to be the key place where this was changed; I grepped sources and it looks like everything is calling this code in the new style, that the setting truly remained "Only for backport compatibility".

I found a similar-sounding bug, https://pad.lv/1853613, which is an issue which was uncovered after the Stein changes to move away from the agent_boot_time config setting. The stein version of this change lands between the neutron repo's 14.1.0 and 14.2.0 tags. UCA has 14.1.0, but not 14.2.0.

Can we get 14.2.0 neutron packaged for stein, especially bionic/stein?

I'm marking this as a duplicate of my stable point release bug that includes Neutron 14.2.0.
