Deleting uploaded files

[gpierre42]

This is a request for adding a method to remove a version of uploaded code in the relevant services (PHP, Java, Generic etc.).

At the moment, the same code upload functionality is re-implemented in every service. This is obviously not a good idea, as duplicate code is hard to maintain. In the longer run it would be good to move this functionality to the ConPaaS core.

The requested delete method, along with CLI support (in cpsclient and cps-tools) was added in commit c7307b4 for the Generic Service and in commit 5f42335 for the hosting services (PHP and Java). The Frontend was updated accordingly in commit c09516e.

I am leaving the issue still open because the code management functionality is, indeed, duplicated: once in the Generic Service and once in PHP/Java (which have a common implementation).
