Re-enable auto upgrade level in nova config

[Gerry Kopec]

To support upgrade code in the pike version of stx-nova in, we had to disable nova config upgrade_levels. This was set by default to compute=auto in openstack-helm.

We should consider reverting to upstream default which should allow for more flexibility during upgrades. Not sure of the impact at this point as this depends on how upgrades will work.

Marking as stx.3.0 as this will only be required on stx.2.0 to stx.3.0 upgrades

@Gerry, what could be our position after we upgrade OpenStack to "Train" version?

[Frank Miller (sensfan22)]

As we are not supporting upgrades from stx.2.0 to stx.3.0 this LP does not need to be addressed in stx.3.0. Re-gating to stx.4.0.

[yong hu (yhu6)]

@zhipeng, please help check this flag compute=auto in nova-config when you upgrade openstack-helm for stx.4.0.

[zhipeng liu (zhipengs)]

We just need to change manifest file.
remove below override in our manifest file
upgrade_levels: None

I will submit patch for it during our openstack upgrade task.

Thanks!
Zhipeng
