GitLab

- Current regex works for dev, master and semvers
- It doesn't work for issue branches

Adapter implementations can override receivedInvalid
to log or report on messages that don't pass validation

I've raised an issue to confirm the schema loads from a
tag once we have created a release to test against.

Take tag/branch/commitref as constructor arg
and retrieve schema from gitlab

+ add catch and retry in poll method

At the moment if the backbone token secret changes
the adapter can have a token it thinks is valid but
which can no longer be decrypted by the backbone.

On a 403 error this will trigger a new token grant
and resend the request with the new token.

+ use response from implicit auth in get auth header

+ refactor cucumber step functions into test folder
+ rename features after tested adapter methods
+ refactor adapter.validate to call adapter.protocol.validate

Add test to check that the mock schema is valid
If the mock schema is not valid then invalid messages
can be marked as valid which makes the tests ineffective

+ Ensure dist modules are built before running tests
+ Test successful receive responses
+ TODO test decode and validate are invoked

+ Return 200 token response for valid credentials
+ Return 403 denied response for invalid credentials

Commit built dist files for now
We can remove these if we publish to npm

Implement rollup to build importable modules
