Update site management

[generoso]

Create an infrastructure for the correct management of the different releases in the update site.

This infrastructure should provide enough storage space to keep all the releases (a github website is not an ideal solution).

This storage system must have a structure like the following:

• a subfolder for each release in the releases folder
• the last stable build in the stable folder

Example:

<some-url>/framesoc/releases/1.0.1/fr.inria.soctrace.maven.repository-1.0.1-SNAPSHOT.zip
<some-url>/framesoc/releases/1.0.2/fr.inria.soctrace.maven.repository-1.0.2-SNAPSHOT.zip
...
<some-url>/framesoc/releases/1.0.7/fr.inria.soctrace.maven.repository-1.0.7-SNAPSHOT.zip

<some-url>/framesoc/stable/fr.inria.soctrace.maven.repository-1.0.7-SNAPSHOT.zip

See, as a reference, this.

Notes:

• at each new release the content of the stable is updated and a new release subfolder is created.
• the script for the update site management (e.g., upload script) must be updated accordingly
• ideally, the upload should be done in the maven deploy phase
