in root Bonita directory to launch start/stop-bonita.sh/.bat

Stop having bonita-web as parent
  - this added gwt dependencies to all modules
  - use bom for dependencies management instead

remove declaration of uid version as it is not used (confirmed by the version
which relates to bonita 7.6)

upgrade plugins versions to latest available
remove unused plugins
  - checksum-maven-plugin
  - jacoco-maven-plugin

update maven-compiler plugin configuration

Introduce bonita-war to replace all-in-one and war-server
  - the main change is to declare all dependencies in war-server to let maven
  resolve dependencies
  - only on community for now
  - previously, as we copied the lib from the web war and add the one for
  bonita-server, the dependencies resolution could not be properly done by maven
  So, now, just copy web resources first to create the initial war, then add all
  the lib to the war via full maven resolution

Simplify the bundle preparation
  - previously, it was done in several steps because we had the deploy and the
  wildfly bundles.
  - now, we create a 'tomcat distribution for bonita', used for both Community
  and Enterprise to remove duplication

Other changes
  - remove license files
  They are only packaged in the deploy bundle but not in the final tomcat one,
  so remove them
  - remove spnego jar from repository and get it as maven dependency
  - package: avoid warning on windows (outputDirectory)

Simplify access to bonita by redirecting tomcat root to the bonita webapps.
This implies replacing the default tomcat ROOT webapps by a custom one in charge
of the redirect.

Part of the work to hide Tomcat internals to the external world.

Deploying extra webapp in the bonita bundle is not supported. However, if this
is needed, do it by dropping it in the webapps tomcat folder
Part of the work to hide Tomcat internals to the external world.

Simplify processing
  - remove version in tomcat directories used in various modules
  - deploy module: put bonita lib directory in the final tomcat server/lib/bonita
  folder for simplification
  - remove extra copies of jars and files

In addition, use maven pom packaging for the 'deploy-distrib-sp'module as
this module doesn't need to produce a jar artifact

* feat(wildfly removal): remove WildFly bundle from distrib

* Also remove CAS config module for WildFly

* Simplify structure, now that there is only Tomcat
