As admin I want to be able to read and increase the embed version

1. Get the version:
GET http://localhost:8080/resources/Version
<Version><Major>1</Major><Minor>6</Minor><Revision>8</Revision></Versio>

To check the value on version.js file:
http://localhost:8080/content/lib/livedesk-embed/scripts/js/version.js

2. Increment the revision for current version:
PUT http://localhost:8080/resources/incrementRevision

3. Reset the revision for the current version:
PUT http://localhost:8080/resources/resetRevision
