Media integration

Be able to create medias from CMIS documents.

• Create a media source plugin for files, the plugin will have the following configuration fields:
  • Select a CMIS field to store a CMIS connection ID and document ID
  • Select a file field to store the CMIS document
  • Storing CMIS connection ID and document ID will allow to re-synchronize the media (if the user want, he/she can create hooks to update or delete the document in CMIS too when updating or deleting the media
• Create a media source plugin for images (inheriting the CMIS file one)
  • Overrides the getMetadataAttributes() and getMetadata() methods
  • Allow to choose an image field instead of a file field
• Create a media source plugin for audios files (inheriting the CMIS file one)
  • Overrides the getMetadataAttributes() and getMetadata() methods
• Create a media source plugin for videos files (inheriting the CMIS audio one)
  • Overrides the getMetadataAttributes() and getMetadata() methods
• Create an action plugin to re-synchronize media and automatically be integrated with VBO
  • If possible, make a configuration option on the action plugin to set a new revision or not (#1104678: Add support for creating new node revision on update by CMIS Sync)
