notify deployment with roll-up naming

Got HTTP 422 while "notify deployment" if using roll-up naming strategy, eg. "MyApp1;MyApp".

>The answer from New Relic support:

>The naming technique where you separate the two 'application' names with a semicolon is a technique that is used by the agent in it's configuration files or api calls. It does not carry over into the Data Rest API, however. If you want the deployment to be inserted for both applications it will be necessary to execute two curl commands, one for each application. This can not be done is a single command.

Its totally transparent for single naming strategy.
If `deployment_name` or `deployment_names` is not set, then `application_name` is a candidate for names split.
