  // General `filter` string syntax:
  // `<field> <operator> <value> (<logical connector>)`
  //
  // *   `<field>` can be `name`, `address`, `port`, or `metadata.<key>` for
  //     map 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:
  //
  // *   `metadata.owner` returns endpoints that have a annotation with the key
  //     `owner`, this is the same as `metadata:owner`
  // *   `metadata.protocol=gRPC` returns endpoints that have key/value
  //     `protocol=gRPC`
  // *   `address=192.108.1.105` returns endpoints that have this address
  // *   `port>8080` returns endpoints that have port number larger than 8080
  // *
  // `name>projects/my-project/locations/us-east1/namespaces/my-namespace/services/my-service/endpoints/endpoint-c`
  //     returns endpoints that have name that is alphabetically later than the
  //     string, so "endpoint-e" is returned but "endpoint-a" is not
  // *   `metadata.owner!=sd AND metadata.foo=bar` returns endpoints that have
  //     `owner` in annotation key but value is not `sd` AND have key/value
  //      `foo=bar`
  // *   `doesnotexist.foo=bar` returns an empty list. Note that endpoint
  //     doesn't have a field called "doesnotexist". Since the filter does not
  //     match any endpoint, it returns no results
  //
  // For more information about filtering, see
  // [API Filtering](https://aip.dev/160).
