This reverts commit 8f2a288c895f2f8f8d13c897b2906aa0c8b57d92.

Because they have the same artifactId of bundles

No need to have guava-testlib in the target platform, since we consume
it as a Maven dependency

* put comment in the right place in the POM

* eclipse-jarsigner-plugin

* eclipse-sign profile in Jenkins

* separate projects for p2 and maven

* harmonized parent with xtext-core parent

* harmonized parent with xtext-extras parent

* prepared sonatype-oss-release profile

* distributionManagement

* prepared Jenkinsfile for Maven deploy

* skipTests in profile sonatype-oss-release

* reference to Maven releng project

* distributionManagement in dev-bom

because it does not inherit from the parent

* updated distributionManagement release repository

separate maven build, tycho test and tycho sign

* coinfigured maven-jar-plugin

to avoid generated sources to be considered as main sources by the
maven-compiler-plugin

* configured exec-maven-plugin

* added source bundles in features

As it used to be in the original

* update to lsp4j 0.20.0

* disable p2 sign in Jenkinsfile

* bumped 2.31.0 in POMs

* xtend-maven-plugin-version 2.30.0
