The container itself was already supporting it. This commit adds tests.

Also added test from docs, which uses default (Java) package.

Remove default namespace from names in sequence test to test implicit default package.

- Error when an invalid argument is passed to shared flag
- Refactor shared handling for actions, packages, triggers, and rules
- Fix update commands to set shared for triggers, and rules
- Remove Publish Functionality From Command that Don't Support it

Since we are going to add the credentials for message hub in the
vcap file, we expect the property "kafka_brokers_sasl" as a list.
That is the reason why we need to get the credentials as a json
object instead of a hashmap.

squashing all review-time commits

Add npm openwhisk package to NodeJS images, and deprecation warning for uses of the 'whisk' context object.

Make OpenWhisk related environment variables available in all container runtimes.

- Do not display the result field from an activation record if it emptyt p

Refactor packages API handler to use new trait and simplify create/update logic.

Mixin ReferencedEntities trait with Rules and Actions API handler.

Update rules tests for new schema.
Use explicit selector on version in fully qualified name of entity.
Refactor entitlement check.
Rename EntitlementService to EntitlementProvider.

Additional tests related to entitlement.

Add tests for binding a private package or trying to get properties of private packages.

- Update action field filter test to expect an exec key

- Allows projections for actions, activations, packages, rules, and triggers

1. Add the new view
2. Make the Controller read from the view
3. Thread the namespace extracted from the view through the API

The general "_" case now resolves to the namespace infered from the key vs. defaulting to the subject's name. For migration of the API, the "old" keys' namespace default to the subject name which preserves previous behaviour.

- Loosen test to reflect reality in the controller
- Add migration entities and test, to be elevated incrementally
- Rename iam.Identities to NamespaceProvider to be more clear

This belongs in an IAM provider interface - so create a new Identities type to host this method.
This refactoring is the first toward allowing multiple namespaces for a subject, each having its own key.
So currently still allow a subject to work acorss any of their namespaces but this will be removed in a future
iteration and hence will break the IAM entanglement with entitlement.

Also fixed some gaps in the Config type which ignored optional properties except when reading from consul.

Fixes issue #1470.

Remove unnecessary var `boundParams` in container and inline `mergeParams` methods.

On failure where action limits are not known, omit limits:null from activation annotation.

Fix action invocation to that getting a container is wrapped in a future and can thus recover properly and not drop annotations from the action. Added test to confirm precense of limits when invoke fails.

Container pool's get action method returned None only when system was shutting down and throwing an exception otherwise. Change the type of the method accordingly to remove the Option and simplify the typing. Make invokeAction complete the transaction and ensure there is at most one completion on the path (ie if the complete transaction operation itself fails, it is not subject to the recovery clause.

Remove unnecessary promise.

Refactor sequence tests. Leave creation and retrieval in core cli, move sequence execution testing to system basictesting

Allow the action proxy to receive a binary 'code' initializer: a base64 encoded string
of a zipped file. Extract the archive to /action to create a new 'exec'.

Add test, and tweak helper test script to allow for testing from the command line.

Add optional zip to BlackBox exec.
Pull dockerskeleton image to invoker (this will also help with black box actions that are based on this image wrt image caching of layers).

Allow --docker to have code property in exec and assume a specific image.
Add support in CLI and recognize openwhisk/dockerskeleton image in backend to bypass pull.
Add unit test.
Remove obsolete exec field. Refactor to remove duplication.
Add test for blackbox action to confirm empty code when no zip given.

- Use build argument to determine whether to cross-compile the CLI
- Use build argument to determine whether or not to run cross-compiled CLI tests

Remove bash script.
