[PATCH v2 00/13] telemetry JSON escaping and other enhancements

[Bruce Richardson <bruce.richardson@intel.com>]

This patchset contains fixes for the problem of handling characters
returned by telemetry callbacks which require escaping when encoded in
JSON format. It also includes unit tests to validate the correct
encoding in such scenarios and a number of smaller enhancements to
telemetry and telemetry testing.

RFC->V2:
* limited characters allowed in dictionary element names and command
  names to side-step the encoding problems there.
* added support for proper escaping of dictionary string values
* added more testing and test cases
* added other misc telemetry cleanups and refactoring
