Enhance SSA ignoreChanges by having better field manager path comparisons

[rquitales]

Proposed changes

This PR enhances the field manager checks to ensure we do not take control of fields manager by other owners during a Patch Resource update. Previously, our set of managed fields only contains that the child node of a path. We now add the parent fields into the set as well.

Example:

Previously:
Set containing currently managed path(s): .spec.metadata.template.labels
Path we want to check if present in set: .spec.metadata.template

Using set.Has(path) will return false. However, this is not wanted since adding .spec.metadata.template as an ignoreChanges path means we don't care about children fields as well.

Now:
set.Has(path) will now return true, which indicates to our provider that we need to ignore spec.metadata.template
