# Ensures all the operator artifacts are created and waits for CSV to succeed.
#
# The following variables must exist:
#
#   removed_operators:    a list of below dictionaries
#     - sub_nspc          subscription namespace
#       sub_name          subscription name
#       csv_name          CSV name to check for
#       pre_cleanup       pre-cleanup tasks, a list of rtypes to remove (ALL)
#         - apiv            api version
#           kind            resource kind
#           nspc            namespace (required for namespaced resources)
#           wait_for_gone   whether to wait for the resource to disappear
#           wait_for_sec    how long (in seconds) to wait for gone
#       add_cleanup       additional CRDs to remove post-uninstall, a list of
#         - name            crd name, OR
#           label           crd label, in case both are defined, both are used
#
# This role must then be applied as:
#
#   - include_role:
#       name: remove-operators
#     loop: "{{ removed_operators }}"
#     loop_control:
#       loop_var: role
#
# What this means is that each item of removed_operators is expected to be
# placed in the "role" variable prior to iterating over this role.
#
# Must include tasks because you can't loop over a block.
