Remove the deployments module altogether?

[fabiobrz]

The deployments module seems to have no more rationale here:

• it was designed originally in the monolithic version in order to reuse application servers (EAP/WildFly) deployments.
• it was then kept in the internal version of the library in order to let both the demos submodule and integration tests depend on them.

Both the above are not requirements here in Intersmash, since there's a testsuite module which could contain the deployments sources.
BTW the testsuite filesystem structure could result in something more similar to the way currently implemented integration tests look like (e.g.: see existing WIldFly/Arquillian tests in the WIldFly testsuite).
A starting point could be what has been done here in Intersmash demos.

• Environment: testsuite
