ContainerSelector selects containers that this policy applies to.
A map of container fields will be constructed in the same way as a map of labels.

A label selector requirement is a selector that contains values, a key, and an operator that
relates the key and values.

to.

operator represents a key's relationship to a set of values.
Valid operators are In, NotIn, Exists and DoesNotExist.
enum:

values is an array of string values. If the operator is In or NotIn,
the values array must be non-empty. If the operator is Exists or DoesNotExist,
the values array must be empty. This array is replaced during a strategic

matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels
