Introduce /clock methods

:Release Notes:
Methods (/clock) for working with different clocks in system.

:Detailed Notes:
Additional /clock methods:
- register clock
- set time for clock
- get time for clock
- get time for clock with fallback and possibility of manual override
- synchronization priority
- replaced single quote with double quote in json encoded params
- etc
Note that deprecated API isn't yet tied with new one (they work almost
independently). I.e. setting user time through /time/setSystemTime
wouldn't set "manual" time source. On the other hand setting
/clock/setTime for "manual" time source will set system time in case
of manual mode enabled or absence of any time setting. etc.

:Testing Performed:
Desktop build. Different /clock/getTime and /clock/setTime with
variations of properties for each functionality.

:QA Notes:

:Issues Addressed:

Tie up /clock and /time for working together

:Release Notes:
Pass through clock change updates from /time methods (like
setSystemTime and setBroadcastTime) to /clock methods.

:Detailed Notes:
- tied up NTP sync in updateSysteTime() together with "ntp" clock
- tied up setSystemTime with "manual" clock
- tied up setBroadcastTime with "broadcast" clock
- added new clock "broadcast-adjusted" to represent broadcast local
  time in current TZ adjusted UTC

:Testing Performed:
Desktop build. Tested manual, broadcast and broadcast-adjusted clocks
update through deprecated way.
