Smarter rebuilding when yaml changes

[stevepeak]

When the oms.yml changes the OMS UI should be smarter on when it should rebuild.

Right now it rebuilds on all changes. However, this is not necessary for most oms.yml changes which are non-operational.

Only update on the following changes to the oms.yml

1. lifecycle.startup
2. environment
3. volumes

All other yaml specifications are non-operational and do not impact the container therefore not requiring it to be rebuilt.
