Merge tag 'v2.0.0' into develop

v2.0.0

Heads-up: Breaking change ahead!

This version changes a hardcoded repository name into a changeable
repository name in the `withMavenSettings.mvnWithSettings()` part. It
does default to `maven-central` though. But if the need arises to choose
a different repository, the new signature looks like this:
```
withMavenSettings.mvnWithSettings nexusCredentials, cesFQDN,
yourDifferentRepositoryName, mvnCallArgs
```

 ### Added
- new lib function for running E2E tests with pure `Selenium` without
the help of `Zalenium`
  - This is addressable with following jenkins pipeline variable:
`withSelenium`
  - Please note that `withSelenium` MUST receive a Docker network
because several containers are started and which must communicate with
each other.

 ### Changed
- signatures for `withMavenSettings` changed slightly so the maven
central mirror can be configured
- helper `generateZaleniumJobName` was renamed to `generateJobName`
   - a delegate method keeps up the backward compatibility
   - Please note that the method `generateZaleniumJobName()` may be
removed in future releases
- `generateJobName` now uses `-` instead of `_` because of possible
problems when used as DNS name

 ### Bugfix

The release v1.2.0 introduced a defect in which the default Nexus mirror
repository name was not properly set. This releases removes this defect
(#9)
