Feature request: 'any' keyword for bearers

[Nick]

Hey,

My favourite feature of the 1.14 release is the ‘any’ keyword for modems and SIMs.  Any chance we can get the same for bearers?

 * mmcli:
   ** Added a new 'any' lookup keyword for the --modem and --sim options, useful
      when the system is only expected to have one single device.

Best,
Nick
