* Replace recordingSpan attributes implementation

Instead of an LRU strategy for cap-ing span attributes, comply with the
specification and drop last added. To do this, the attributesmap is
replaced with a slice of attributes.

* Remove attributesmap files

* Refine addition algorithm

Unify duplicated code.

Fix deduplication algorithm.

Fix droppedAttributes to always be returned, even if the span has no
attributes.

* Unify span SetAttributes tests

* Doc fix to attr drop order in changelog

* Test span and snapshot attrs

* fix lint

* Add tests for recordingSpan method defaults

* Comment why pre-allocation is not done

* Correct grammar in recordingSpan allocation comment

* Update sdk/trace/tracer.go
