Deployment spec properties are inadvertently removed when serializing
Summary
Various valid deployment spec properties are seemingly wiped out when I load it into a V1DeploymentSpec object, make a small change, then re-serialize to a dict.
Details
I am extracting a V1DeploymentSpec from a ClusterServiceVersion manifest, making a small mutation to it, then re-serializing it and adding it back into the ClusterServiceVersion. This leads to multiple mutations that were not intended. See the following sequence of diffs (none of which were intended) for reference:

@whatsacomputertho What i understand from the description is that you are trying to load the specs from ClusterServiceVersion manifest and making small mutations, but with those mutations other unexpected mutations happen, could it be due to you loading the mutations to another V1DeploymentSpec object, which then reinitializes the other states of the objects to the state that they were defined as? such as with selector : {}?
