Maintenance Process for `silverpond/aiko_services`

[rskew]

silverpond/aiko_services/master should be the same as upstream geepscape/aiko_services/master with a few of our commits at the top adding functionality we need for Highlighter. Each commit should be associated with an upstream PR, listed below.

To update the version of upstream we use, rebase master onto upstream master, e.g.:

git pull --rebase origin-geekscape master
git tag -a  v0.6.postN
git push --force-with-lease origin-silverpond master
git push --tags origin-silverpond master

Don't forget to update the version in pyproject.toml to match the tag.

As our changes are addressed in geekscape/aiko_services/master, rebase silverpond/aiko_services/master to remove our old version of the fix, and remove the PR from this list.

v0.6.post7: Modified the commit of the "Notify stream-creator of stream stop" feature

• fix a bug where the stream-stop notification masked an error state
• don't notify when there is an error state as the usual frame_complete notification will work better in this case

[rskew]

I've updated the notify-stream-creater-of-stream-stop feature:

• pass diagnostic from _process_stream_event to destroy_stream so the stop-stream message can include a diagnostic produced by start_stream
• don't break early when calling stop_stream in destroy_stream, allow all elements to clean up
• feed the error state back in to stop_stream in destroy_stream so all elements know why a stream has ended, and upstream stop_streams can engage the error condition
• notify listeners via queue_response and topic_response of the stream stopping in all cases, not just when there is no error condition

Extra unrelated feature: Exit from process_frame calls when the stream does not exist. This is required as when processing video, many process_frame calls are queued up in the mailbox, and they may get executed after a stream has stopped due to an error.

I amended the single commit for this feature, I probably should have added a new one instead.

Update to v0.6.post13: Add a commit that changes the version in pyproject.toml, enabling us to do an extra check when installing that we're getting the version we expect.

v0.6.post22 fixes a bug where the stream lock is not released when an exception is thrown in the frame generator
(I first made v0.6.post19 and v0.6.post20 and v0.6.post21 but had to make further updates due to forgetting to update the version in pyproject.toml, and fixing further problems in the test)

Upstream PR: geekscape#45

v0.6.post25 Adds more hooks and fixes a bug in PR 45 that leads to a crash due to locks being released twice

Upstream PR: geekscape#46

v0.6.post26 has associated upstream PRs:

• Add support for URLs with scheme 'data:' geekscape/aiko_services#48
• Set default value for the 'use_create_frame' argument to a data sources' start_stream() method to False, making the use of create_frames() the default geekscape/aiko_services#49

v0.6.post27 Reverts the change in PR 28 that prevents creating frames when the stream hasn't been started, as this breaks remote pipeline elements
