Auto connections for pcsc-daemon

pcsc-daemon is a snap that bundles the pcscd smartcard/NFC daemon from the pcsc-lite package, the matching library and the acsccid and ccid USB drvers into one snap.

To detect smartcard/NFC readers on USB the snap needs to be connected to the raw-usb and hardware-observe interfaces.

I’d like to request auto.connection for both of these interfaces.

Additionally pcsc-daemon also provides a content interface that gives connected snaps r/w access to the pcscd socket.
I’d like to request a store declaration for auto-connection of this interface for all possible consumers here as well (so snaps from other maintainers can use pcsc-daemon as default-provider and get the snap auto-installed)…

An example consumer snap can be found here:
