35cfbc7e87 Update precedence of event name in Jaeger exporter (#1768)
* Update precedence of event name in Jaeger exporter

The OTel specification states that the event needs to be recorded as a
log with its name set to a tag having the "event" key. That key needs to
be overridden when there is an attribute with the same key. This updates
to implement this.

Resolves #1767

33699d242d Adds semantic conventions for exceptions (#1492)
Adds support for the opentelemetry exceptions semantic conventions. In
short, this has RecordError produce an exception event with exception
attributes instead of using the error event and error attributes.

While golang does not have exceptions, the spec itself does not
differentiate between errors and exceptions for recording purposes.
RecordError was kept as the method name, both for backwards
compatibility and to reduce confusion (the method signature takes in a
golang error object). The spec appears to allow this, as it suggests the
method is optional and signature may reflect whatever is most appropriate
for the language implementing it.

It may seem non-intuitive to log an exception event from a method called
RecordError, but it's beneficial to have consistent behavior across all
opentelemetry SDKs. Downstream projects like the opentelemetry-collector
can build off of the published API and not special case behaviors from
individual languages.

20c93b01eb Update SamplingParameters (#1749)
* Update SamplingParameters

Remove HasRemoteParent fields from SamplingParameters. The
HasRemoteParent field is a duplicate of the Remote field of the parent
span context contained in the ParentContext.

Change the `ParentContext` field from storing a `SpanContext` to a
`context.Context` that holds the parent span. This is to conform with
the OpenTelemetry specification and resolve #1727.

97501a3fee Update SpanSnapshot to use parent SpanContext (#1748)
* Update SpanSnapshot to use parent SpanContext

the parent was remote does not provide a comprehensive view of the
parent span nor is it an efficient way to transmit this information.

parent span context. This field replaces the ParentSpanID and
HasRemoteParent fields.

604b05cbcf Store current Span instead of local and remote SpanContext in context.Context (#1731)
* Store Span instead of local/remote SpanContext in Context

Now that the SpanContext has a remote identifier, storing a Span's
SpanContext two separate ways in a Context (one for local another for
remote) is unnecessary and adds complication throughout the project when
determining heredity of a Span. This moves to storing the Span directly
in the Context uniformly (for both local and remote) as current Span. In
the process, it updates the getter/setter functionality the `trace`
package provides and replaces the distributed heredity logic throughout
the project with just using the current Span as the parent if it exists.

4beb70416e sdk/trace: removing ApplyConfig and Config (#1693)
This patch removes `ApplyConfig` method and `Config` struct from
`go.opentelemetry.io/otel/sdk/trace` package.  To ensure valid config
for TracerProvider, it adds `ensureValidTracerProviderConfig` private
function.
Jaeger and Zipkin have been used the `Config` directly across package
boundaries. Since `Config` is removed, they can't use it. This change,
thus, replaces `WithSDK` with `WithSDKOptions`.

Resolves #1636, #1705.

1d42be1601 Rename WithDefaultSampler TracerProvider option to WithSampler and update docs (#1702)
* Rename WithDefaultSampler TracerProvider option to WithSampler

The term "DefaultSampler" comes from early ideas of this project where
there would be overriding samplers lower in the trace SDK. This
overriding does not exist and if it is going to be introduced in the
future the sampler associated with the TracerProvider is already scoped
based on that association (no need to scope with a name). This renames
the TracerProvider option to not include this anachronism.

* Update PR number in CHANGELOG

* Propagate rename

* Update defaults documentation for TracerProvider

* Update sdk/trace/provider.go
