Initial implementation of Telemetry service

Implemented main application of Telemetry service.
Added ReportManager interface. Added MaxReports and
PollRateResolution properties to ReportManager interface.
Implemented simple logger.

Tested:
 - Built without Yocto and ran on x86 platform with success
 - Added telemetry to romulus image using
   recipe-phosphor/telemetry from meta-phosphor repository
 - Started as service in romulus image in QEMU with success
 - Verified that all added properties are present in dbus
