having it connected from the very beginning.

utils: streamproducer: Remove StreamProducer::forward()
...
Most applications forget to call `forward()` in the beginning and then
nothing works.

utils: streamproducer: Add #[must_use]
attribute to add_consumer()
...
Simply discarding the result will immediately disconnect it again, which
was likely not intended and can easily lead to bugs.

utils/streamproducer: add ConsumptionLink
...
Having an explicit link object makes it much easier to build complex
producers/consumers dynamics graphs.
It provides helper to switch producers and prevent accidentally keeping
broken links around as they are disconnected on Drop.

User may want to plug another producer when one is eos, in such case we
don't want to propagate eos to consumers.

utils/streamproducer: Add StreamProducer::configure_consumer()
...
This allows configuring an `appsrc` before actually adding it as
consumer at a later time, and can be useful if the pipeline with the
source should be started earlier than adding it to a consumer.
Also use strongly-typed property API for the `appsrc` properties.

Introduce StreamProducer
...
Introduce a new `gstreamer-utils` crate where we implement a
`StreamProducer` structure that allows "producing" pipeline (Producers)
pushing their data to 0 or several "consuming" pipelines. The Producer
needs to push their data to an `appsink` which the `StreamProducer` controls
and the "consumer" pipelines need to have an AppSrc which the same
StreamProducer controls.
It allows similare behavior as a `tee` element but with a simpler to
handle addition and removal of "consumers" as well as a total decoupling
of the various consumer, both between each others and the producer
pipeline.
