[#PETALSESBCONT-249] Move the WS API as an extension of the Petals ESB container - Petals Link JIRA

Description:

The WS API is not a required internal component to run the Petals ESB container. So it can be provided as an extension.

Depends

This issue depends on:
~~PETALSESBCONT-226~~ Move the artifact repository as an extension of the Petals ESB container
~~PETALSESBCONT-250~~ The topology service uses the WSAPI

This issue blocks:
~~PETALSESBCONT-252~~ The HTTP server Jetty embedded into the Petals ESB container should be an extension
~~PETALSESBCONT-253~~ Create a Debian package to install the Petals ESB WS-API
~~PETALSESBCONT-303~~ Move the configuration of the WS-API extension from topology definition to the local container configuration
