Add support for new controlHint and labelHint properties in back-end

The problem

We have support for these new properties in our form factory provider service, but until they are “a thing” in the back-end we can’t use them in our model driven forms.

Until this happens, and after https://github.com/syndesisio/syndesis/pull/1664/ has been merged, we’ll notice a “regression” in our model driven forms where what used to be tooltip text attached and duplicated across a label and its form control counterpart will become description text that renders below a given form control.

Merging https://github.com/syndesisio/syndesis/pull/1664/ before this is in place will cause our model driven forms to come out of sync with our UX designs until these properties are updated to use the new *correct property names in the various *.json files.

It’s the last puzzle piece for resolving https://github.com/syndesisio/syndesis/issues/992

Expected behavior

The properties labelHint and controlHint in app/connector/activemq/src/main/resources/META-INF/syndesis/connector/activemq.json and similar type files, should be provided as part of the payload with the rest of the form properties.

API Endpoints and Schemas

/api/v1/connectors

Tasks involved / Steps to Reproduce

1. Specify a labelHint property in app/connector/activemq/src/main/resources/META-INF/syndesis/connector/activemq.json for any form property, for example brokerUrl
2. Begin watching network traffic in your browser dev tools
3. Begin adding an AMQ connection, and when you get to the configuration screen, notice the tooltip doesn’t show up
4. Also notice the call to https://syndesis.x.x.x.x.nip.io/api/v1/connectors didn’t return the new property.

@seanforyou23 the backend needs to add those fields to ComponentDefinition.Property interface. Working on it now.

I just referenced #992 when I posted the PR since it was pretty much leftovers from that work anyway. Hope that’s ok.
