Auto-connection request for piconn

My snap piconn need to auto connect to runtime-dir interface provided by the crossbar snap.

I am the upstream for both snaps

Here is a pull request that added runtime-dir interface to crossbar snap https://github.com/crossbario/crossbar/pull/1635

+1 from me as reviewer though we’ll need to wait for more eyes on this from reviewers (similar to Auto-connection request for deskconnd)

Also, cross-publisher auto-connects are somewhat tricky, I’d like Jamie’s take on that.

Cheers,

Daniel

Since you are (effectively) the same publisher, I have granted auto-connect to piconn. This is now live. Please verify the auto-connect is working correctly as well as auto-connection for the socket directories these snaps provide.
