Feature/publish to broker

[markozz]

Hi,

With this pull request I would like to contribute the following feature to the pact-JVM-server;

• publish a contract which is created on disk to a pact broker.

By running the pact-jvm-server with parameter -b "https://valid.pact.broker.com" and optionally -t "val!dT0ken" a call to the endpoint /publish will push the contract from disk to the broker.

Please let me know what you think!

Kind regards,

Mark

LGTM.

There is a PactBrokerClient class in core/pactbroker module that would be better to use, as it uses HAL links navigation instead of templating the URI and also supports tagging the pact version.

Here is an example of it being used.

I guess the tags would be an extra attribute on the body.
