Create instance type profiles

Following the profile introduction: NXP-29190 we now want to create the following profiles:

• front
• back
• import

They will be both implemented as a Nuxeo Template.

The three profiles should be distinct, aka enabling them at the same time will lead to startup issues.

Front profile

The front profile should make the Nuxeo node a specialized one without having too heavy async tasks in order to privilege the web traffic.

Back profile

The back profile should make the Nuxeo node a specialized one without having to handle the web traffic.

Note: Security to not access the node from the outside should be made on the infrastructure.

Importer profile

The importer profile should make the Nuxeo node a specialized one without having to handle the web traffic, without having to handle the tasks generated by front and/or back Nuxeo nodes. Like it, the importer profile should declare some namespacing for the tasks it generates.
