(::String) — Optional. The filter to list results by.
General filter string syntax:
<field> <operator> <value> (<logical connector>)
<field> can be name, labels.<key> for map field, or
attributes.<field> for attributes field
<operator> can be <, >, <=, >=, !=, =, :. Of which :
means HAS, and is roughly the same as =
<value> must be the same data type as field
<logical connector> can be AND, OR, NOT
Examples of valid filters:
labels.owner returns namespaces that have a label with the key
owner, this is the same as labels:owner
labels.owner=sd returns namespaces that have key/value owner=sd
name>projects/my-project/locations/us-east1/namespaces/namespace-c
returns namespaces that have name that is alphabetically later than the
string, so "namespace-e" is returned but "namespace-a" is not
labels.owner!=sd AND labels.foo=bar returns namespaces that have
owner in label key but value is not sd AND have key/value foo=bar
doesnotexist.foo=bar returns an empty list. Note that namespace
doesn't have a field called "doesnotexist". Since the filter does not
match any namespaces, it returns no results
attributes.managed_registration=true returns namespaces that are
managed by a GCP product or service

API Filtering.
