Allow Collections to be Mutated

As of Server 7.2.0, it is now possible to mutate a Collection in order to enable History Retention. This change needs to be reflected in CAO.

Temporary Workaround

Because collections are immutable, operator only checks for presence once created.  You can modify an existing collection using the following command:

curl localhost:8091/pools/default/buckets/my_bucket/scopes/_default/collections/c1 -u Administrator:asdasd -X PATCH -d history=false 

Operator will not modify this value once set.
