Stop polling for updates to telemetry data from
TelemetryController when scope is destroyed.
Addresses some performance issues observed in
WTD-614, autoflow tabular views (although this
view doesn't use TelemetryController directly,
the continuing of this polling in the background
can slow down updates when it is showing.)
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.
