that suits the docker version, as it is different from the distrib one.
For now, the version is copied, and any modification in the file must
be copied to the docker version.
With the proposed change, the docker version is generated from the
distrib version, with minor changes

that index.jsp was added to replace root application and to redirect to
/bonita

Because of a refactor on how distrib is organized, that index.jsp was
not copied anymore in `/server/webapps/ROOT`

Move it in the right folder and change the order of copy to have it
where it belongs.

* avoid generating empty log files

'host-manager' and 'manager' webapps are not packaged within the bundle so
remove associated handlers that previously generated empty log files.
In addition, remove the 'localhost' handlers as no logger is associated to it.

* all logs in a single bonita.log file

This ensures that all logs of 3rd party libs are in bonita.log and simplify
logging configuration.

In the past, we have been forced to declare for most of 3rd party lib loggers
the right handler to ensure logs are generated in the bonita.log file. Most of
the time, this was done only after receiving external feedback on bug
investigations (information were lost or hidden in catalina log file).

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

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)
