glance services always restart on updates(Newton)

[Pranali Deore]

Description of problem:

When applying updates, glance services restart on the controllers even if no changes are made.

It seems that we may have fixed this in subsequent releases but is still occuring in Newton. I think it may be related to HA controllers as the following are removed in step3 and readded in step4:

Step3:
