* Drop WorkerCount option
This is not a good option - the user isn't likely to know how many
worker goroutines is optimal. This should be something that an
exporter should figure out itself. The second problem with the option
is that it is specific to the metric transformation from SDK export
format into protobuf. When the exporter starts supporting other
protocols (HTTP/JSON for example), this option may be of no use. So
the option should rather belong to the protocol, not to the
exporter. Currently both mean the same, but later they will be
separated, and this option breaks the separation.
* Make stop channel a typical signalling channel
Signalling channels are idiomatically defined as chan struct{}, so
let's make it so, to avoid confusion about the meaning of the bool
type.
* Close a race when grpc connection is closed multiple times
If several goroutines call Shutdown at the same time, then the
following scenario is possible:
goroutine A locks a mutex, reads a started member, unlocks the mutex
and gets preempted
goroutine B locks a mutex, reads a started member, unlocks the mutex
and gets preempted
goroutine A does not return early in the "if !started" conditional and
continues to close the connection and execute the rest of the function
(where it finally sets the started member to false), gets preempted
goroutine B also does not return early, because it got a copy of
started before goroutine A set it to false, so it tries to close the
connection again.

* Add parent context to SpanProcessor.OnStart
The spec requires doing so. Right now SpanProcessor implementations
aren't doing anything with this argument.
* Update changelog
* Fix typo in test name
* Move registry package under metric
* Move Number type to the metric/number subpackage
This also renames NumberKind type to Kind.
* Update changelog
* Drop outdated comment
* Export non monotonic counters as gauge values from the prometheus exporter
* Add a test to ensure the pre-existing LastValue pathway on the collector exports the last value
* Add a TODO around refactoring the prometheus test to verify metadata as well

* Update Span End method documentation
Updates to the Span after End is called result it potentially
inconsistent views of the Span between the code defining it and the
ultimate receiver of the Span data. This corrects the documented
language of the API to prevent this from happening.
* Add changes to changelog
Remove cruft about spanStore.
Update documentation about how span.mu is used (related to #1311).
Reformat to conform with idiomatic field documentation.
* Update README
Move project status to top of project documentation and add explicit
warnings that this project may introduce breaking changes.
* Add disclaimer to public packages docs
* Use explicit warning in README
* Remove quotes from UnmarshalJSON

* Update Span API event methods
Remove the context argument from the event methods. It is unused and can
be added back in as a passed option if needed in the future.
Update AddEvent to accept a required name and a set of options. These
options are the new EventOption type that can be used to configure a
SpanConfig Timestamp and Attributes.
Remove the AddEventWithTimestamp method as it is redundant to calling
AddEvent with a WithTimestamp option.
Update RecordError to also accept the EventOptions.
* Add changes to CHANGELOG
* Add LifeCycleOption
Use the LifeCycleOption to encapsulate the options passed to a span for
life cycle events.
