This implements specification requirement:
https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#resource-creation
- Changes `resource.NewWithAttributes` to require a schema URL. The old function
is still available as `resource.NewSchemaless`. This is a breaking change.
We want to encourage using schema URL and make it a conscious choice to have a
resource without schema.
- Merge schema URLs acccording to the spec in resource.Merge.
- Several builtin resource detectors now correctly populate the schema URL.

* Removed different types of Detectors for Resources.
This change simplifies different types of collectors into one list. The
order of this list determines how they are applied. Defaults are
applied when the user does not supply any detectors. To achieve
default behavior and additional behavior a DefaultDetectors struct has been
created
* missed prometheus test.
* Changed behavior around WithDetectors(nil)
Added examples of use of WithDetectors.
* Added NoOp example
* Changed test to reflect acutal default case
This changes because WithDetector() no longer is the same as not using WithDetector()
* Unexports the noOp detector
* Updated changelog
* Fixes to spelling mistakes.
* Added NewEmptyResouce and unexported builtin detectors
* Fix for prometheus example

* Rename resource pkg label vars and methods
The former `labels` package is now named `attributes` to conform with
the specification requirement. This removes the lingering `label` term
from the `resource` package.

* Update PR number in CHANGELOG
* Propagate rename to the prometheus exporter pkg
