Allow supervisor to be accessed locally through API

Close for Icefish 9.0.0 RC1

Do you want the message to have the lower level INFO ?

No.

The supervisor has 2 inputs:

• one that is the supervision api that allows to create programs that use the supervisor. This is the one that this ticket is related. It is of path /run/platform/apis/ws/supervisor as can be seen on the review linked here

• one is the link from the supervised binders to the supervisor. when the supervisor is not started, you have the message.

I'm wondering, is this related to messages like these:

afbd-agl-service-network@1.0-cc34edb[3936]: NOTICE: Can't acces socket path /run/platform/supervisor: No such file or directory /ws/scottm/dev/agl/agl-repo/build-m3ulcb/tmp/work/aarch64-agl-linux/af-binder/master+gitAUTOINC+51ab7c2f95-r0/git/src/afb-supervision.c:164,try_connect_supervisor

that I'm seeing a lot on latest master?

Please cherry pick to halibut branch. This was merged to master after halibut branch created.

EDIT: No need to cherry pick to halibut. New feature for Icefish.
