Add ability to subscribe/unsubscribe to streaming
telemetry updates. This may be more performant than
polling in some circumstances, and appears necessary
for good performance of autoflow tabular views,
WTD-614.
Move implementation of formatter used for display
of domain values out of plot, and into the telemetry
bundle, from which it can be exposed as a general-use
service. WTD-599.
Return the same value from getTelemetryObjects if thes e
haven't changed, to permit this return value to be
watched directly without appearing unstable. Supports
the addition of stacked plot controls, which need
to be conditioned on the number of telemetry objects
present. WTD-625.
Bring in initial state for the platform/telemetry
bundle, which provides general-purpose telemetry
conventions and infrastructure to support creating
domain objects which expose telemetry data.
WTD-575.
