Add support for Resources in the SDK (#552)
* Add support for Resources in the SDK

Add `Config` types for the push `Controller` and the `SDK`. Included
with this are helper functions to configure the `ErrorHandler` and
`Resource`.

Add a `Resource` to the Meter `Descriptor`. The choice to add the
`Resource` here (instead of say a `Record` or the `Instrument` itself)
was motivated by the definition of the `Descriptor` as the way to
uniquely describe a metric instrument.

Update the push `Controller` and default `SDK` to pass down their configured
`Resource` from instantiation to the metric instruments.

* Update New SDK constructor documentation

* Change NewDescriptor constructor to take opts

Add DescriptorConfig and DescriptorOption to configure the metric
Descriptor with the description, unit, keys, and resource.

Update all function calls to NewDescriptor to use new function
signature.

* Apply suggestions from code review

Co-Authored-By: Rahul Patel <rghetia@yahoo.com>

* Update and add copyright notices

* Update push controller creator func

Pass the configured ErrorHandler for the controller to the SDK.

* Update Resource integration with the SDK

Add back the Resource field to the Descriptor that was moved in the
last merge with master.

Add a resource.Provider interface.

Have the default SDK implement the new resource.Provider interface and
integrate the new interface into the newSync/newAsync workflows. Now, if
the SDK has a Resource defined it will be passed to all Descriptors
created for the instruments it creates.

* Remove nil check for metric SDK config

* Fix and add test for API Options

Add an `Equal` method to the Resource so it can be compared with
github.com/google/go-cmp/cmp.

Add additional test of the API Option unit tests to ensure WithResource
correctly sets a new resource.

* Move the resource.Provider interface to the API package

Move the interface to where it is used.

Fix spelling.

* Remove errant line

* Remove nil checks for the push controller config

* Fix check SDK implements Resourcer

* Apply suggestions from code review

Add observer metric (#474)
* wip: observers

* wip: float observers

* fix copy pasta

* wip: rework observers in sdk

* small fix in global meter

* wip: aggregators and selectors

* wip: monotonicity option for observers

* some refactor

* wip: docs

needs more package docs (especially for api/metric and sdk/metric)

* fix ci

* Fix copy-pasta in docs

Co-Authored-By: Mauricio Vásquez <mauricio@kinvolk.io>

* recycle unused recorders in observers

if a recorder for a labelset is unused for a second collection cycle
in a row, drop it

* unregister

* thread-safe set callback

* Fix docs

* Revert "wip: aggregators and selectors"

This reverts commit 37b7d05aed5dc90f6d5593325b6eb77494e21736.

* update selector

* tests

* Rework number equality

Compare concrete numbers, so we can get actual numbers in the error
message when they are not equal, not some uint64 representation. This
also uses InDelta for comparing floats.

* Ensure that Observers are registered in the same order

* Run observers in fixed order

So the tests can be reproducible - iterating a map made the order of
measurements random.

* Ensure the proper alignment of the delegates

This wasn't checked at all. After adding the checks, the test-386
failed.

* Small tweaks to the global meter test

* Ensure proper alignment of the callback pointer

test-386 was complaining about it

* update docs

* update a TODO

* address review issues

* drop SetCallback
