cdba-server: Introduce helper for sending measurements The current format of the cdb_assist backend status messages was never intended to be parsed by a non-human, and the format doesn't extend well to other backends. Extend the format to be formatted as a json string, with a timestamp, implemented in a separate status module. The button status is skipped from the new status message, as it reflect the output-values as set by cdba itself, rather than any measured state. The timestamp is offset to the first measurement, to avoid disclosing the uptime of the machine cdba-server is running on.

cdba-server: Allow external status command While the CDB Assist and QcomLT Debugboard is measuring voltage and current on the DC jack directly in the backend, other backends and further measurements can be performed using custom tooling. Introduce support for invoking an external "status-cmd" to produce such status updates. The status command should on its stdout produce json-formatted status updates following the same format as the cdba-server: {"ts":%d.%03d, "name": {["mv"\|"ma"]: %u}(, "name2": {["mv"\|"ma"]: %u})*} with the ts aquired using clock_gettime(CLOCK_MONOTONIC) and provided in seconds and milliseconds since the first measurement.
