delta-find: move the emotion of parents in a dedicated method

After splitting the filtering, and with the `_candidate_groups` layer removed,
we can start splitting the group generation too. This helps to organize this
code and make it easier to modifying the future.

# A utility extension that help taking a break during streamclone operation
#
# This extension is used through two environment variable
#
# HG_TEST_STREAM_WALKED_FILE_1
#
#   path of a file created by the process generating the streaming clone when
#   it is done gathering data and is ready to unlock the repository and move
#   to the streaming of content.
#
# HG_TEST_STREAM_WALKED_FILE_2
#
#   path of a file to be manually created to let the process generating the
#   streaming clone proceed to streaming file content.
