Tyler Goodlet c3682348fe Use the actor's service nursery instead
In order to ensure the lifetime of the feed can in fact be kept open
until the last consumer task has completed we need to maintain
a lifetime which is hierarchically greater then all consumer tasks.

This solution is somewhat hacky but seems to work well: we just use the
`tractor` actor's "service nursery" (the one normally used to invoke rpc
tasks) to launch the task which will start and keep open the target
cached async context manager. To make this more "proper" we may want to
offer a "root nursery" in all piker actors that is exposed through some
singleton api or even introduce a public api for it into `tractor`
directly.

Tyler Goodlet cae7f486e4 Revert "Lol, don't use `maybe_open_feed()` for now, it's totally borked..."
Think this was fixed by passing through `**kwargs` in
`maybe_open_feed()`, the shielding for fsp respawns wasn't being
properly passed through..

This reverts commit 2f1455d423.

Tyler Goodlet ff322ae7be Re-impl ctx-mng caching using `trio.Nursery.start()`
Maybe i've finally learned my lesson that exit stacks and per task ctx
manager caching is just not trionic.. Use the approach we've taken for
the daemon service manager as well: create a process global nursery for
each unique ctx manager we wish to cache and simply tear it down when
the number of consumers goes to zero.

This seems to resolve all prior issues and gets us error-free cached
feeds!

Tyler Goodlet a7d3afc9b1 Add a `maybe_open_feed()` which uses new broadcast chans
Try out he new broadcast channels from `tractor` for data feeds
we already have cached. Any time there's a cache hit we load the
cached feed and just slap a broadcast receiver on it for the local
consumer task.
