Add ability to parse Schema files according to OTEP 0152 (#2267)
* Add ability to parse Schema files according to OTEP 0152

The parser and parsed representation (AST) are placed in a separate
Go module so that they are can be consumed independently without
the need to bring the rest of the SDK.

Ability to use the parsed representation for schema conversions
can be added later.

* Fixes based on PR comments

* Rename "label" to "attributes"

See https://github.com/open-telemetry/oteps/pull/181

* Fixes based on PR comments

* Add README.md

* Wrap the error in Parse()

* Add docs for exporter types

* Use yaml.NewDecoder

* Verify parsed content in the test

* Fix indentation in README example

* Fix README spaces vs tabs

* Correctly space imports

* Add heading to README
