[WIP] Tasks code improvements
Tidies up many things about tasks
* different types of execution follow the same code path
* scheduled tasks are tracked better
* remove deprecation
* optimize task execution, including removing soft references in submitters
* indicate (with `TODO`) where downstream improvements should be made
WIP here:
* clean up "schedule task" API
* wait for 0.12.0 RC branch (this should be done early in the next release
cycle)
This is prep work for the main event (which will be done in separate PRs):
* improve the tasks tree so ops users can explore it more naturally, esp
for init, publishing, and scheduled tasks
* tag tasks running by adjuncts so they can be retrieved

diff task submisson paths share code about how to end, and tidy listeners
fix bug where some where executed and GC'd before the child had actually

by ensuring listeners don't run until the task recognizes the cancellation.
also tidy how end code is shared, and remove deprecation
