* Rename *Provider names
There is overlap in naming with MeterProviders and TracerProviders. This
is means the specification is not implemented and these types can not
exist in the same package (#1179). This makes each type and related
functions and types explicit.

* PR feedback
- More clearer naming of structs; add comments where missing
- Adhere to the configuration style guide
* PR feedback - punctuation
* Convert XConfigure into constructors
Previously, we discussed the possibility of converting
the config types into internal ones. But due to the
cyclic dependencies it introduces, we are only
converting XConfigure into constructors and document that
XConfig types are most likely are not going to be directly
used by developers.
In package documents, constructors will be nicely listed
under the config types and they won't be yet another
standalone symbol developers need to learn about.
Fixes#1130.

* Move content length out of basic attributes
semconv.httpBasicAttributesFromHTTPRequest() was including the request's content length,
which is a high-cardinality label. It ended up in metric labels through the use of that function
by semconv.HTTPServerMetricAttributesFromHTTPRequest().
* Add CHANGELOG entry
Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com>
http.ResponseWriters may implement additional interfaces
(http.CloseNotifier, http.Flusher, http.Hijacker, http.Pusher,
io.ReaderFrom) that get lost when the ResponseWriter is wrapped in
another object. This change uses the httpsnoop package to wrap the
ResponseWriter so that the resulting object implements any of the
optional interfaces that the original ResponseWriter implements as
well as using the replacement ResponseWriter methods that gather
information for tracing.
* Remove otel/sdk dependency from grpctrace
Use otel/trace/testtrace instead and cleanup testing code.
* Update httptrace to not depend on the SDK

* Update grpctrace instrumentation span names
Span names MUST not contain the leading slash (`/`) that the grpc
package prepends to all `FullMethod` values. This replaces the
`serviceFromFullMethod` function with a parsing function. This parsing
function returns an span name adhering to the OpenTelemetry semantic
conventions as well as formatted span attributes.
Additionally, the service name needs to include the package if one
exists. This updates that attribute accordingly.
Once #900 is merged the method attributes can be added by uncommenting.
Resolves#916

* Correct B3 propagators and add tests
* Break up external integration and internal unit tests
* Add changes to Changelog.
* Update Changelog with PR number
* Fix lint issues
* Update trace flags
Add a new "not sampled" mask to complement the existing "sampled" one.
Rename `FlagsUnused` to `FlagsUnset`.
Add documentation for each of the flags to help understand their
purpose.
* Update extractSingle to support unset sampling
* Update existing tests to appropriately use FlagsUnset
* Remove bogus debug flag test
The B3 specification states "Debug is encoded as `X-B3-Flags: 1`. Absent
or any other values can be ignored", so testing of other values should
not result in an error.
* B3 Extract now supports parsing both headers
Remove test cases that would fail if the fallback header format was
expected to not be used.
* Feedback
* Switch to bitmask inject encoding field
Add the B3Encoding and valid HTTP based values. Change the B3 propagator
to use these bitmask fields to specify the inject encoding it will
propagate.
* Add comments
* Migrate B3 integration tests to existing testtrace
* Update comment
* Benchmark invalid B3 injects as well
* Update trace flags
Add a FlagsDebug and FlagsDeferred to track the B3 trace state.
Add helper methods to the SpanContext to check the debug and deferred
bit of the trace flags.
Update SpanContext.IsSampled to return if the sampling decision is to
sample rather than if the sample bit is set. This means that if the
debug bit is also set it will return true.
* Revert SpanContext.IsSampled back
* Add comment to b3 test data generation
* Update Changelog
* Fix trace flag name in Changelog
* Fix Changelog formatting
* Update Changelog
* Remove valid check at start of B3 injectg
This check makes sample only headers not propagate.
* Update B3 inject integration tests
Use the passed SpanContext and check directly the span ID.
* Update B3 integration tests
Run update checked SpanID to match sent.
Add tests to validate sample only transmissions and debug flag support.
* Rename injectTest parentSc to sc
This is no longer the parent.
* Update GetAllKeys for B3
* Un-Export the B3 headers
The B3SingleHeader name will conflict with the upcoming change to prefix
the SingleHeader encoding with "B3". There are a few options to address
this conflict, but in the end we do not need to be exporting these
values. They are duplicates of the OpenZipkin package and users should
use those.
* Rename B3 encodings and move support method to B3Encoding
Include a `B3` prefix to scope the encoding names.
Move the related support method to the B3Encoding itself, instead of the
B3 propagator.
Add tests to provide a sanity check for encoding bitmasks.
* Update span_context_test tests
Update test name to better describe how unused bits have no affect on
the sampling decision. Include the inverse of this test as well: not
sampled but has unused bits.
* Use named const for Single Header decoding widths
* Update api/trace/b3_propagator.go

* Update B3 header names
Correct the B3 single header name from `X-B3` to `b3`.
Use the lowercase version of the B3 multiple headers. This is based on
the fact that HTTP headers are case-insensitive, however, other
protocols may not be.
* Update Changelog
