Description

This implements the Filter field on pbcatalog.WorkloadSelector to be a post-fetch in-memory filter using the https://github.com/hashicorp/go-bexpr expression language to filter resources based on their envelope metadata fields.

All existing usages of WorkloadSelector should be able to make use of the filter.
