Maven Central is blocking our IP address when we use maven via bndtools

Seems like Maven Central modified their protection yesterday. Since yesterday, our builds are often failing because the downloading of maven libraries fails.

I discovered that it's triggered by an invalid User-Agent. When we proxy the requests through an reverse proxy and modify the User-Agent to match the original maven User-Agent in style of "Apache-Maven ...", it works.

Original maven is using a custom user-agent, configured here: github.com/apache/maven/blob/master/impl/maven-core/src/main/java/org/apache/maven/internal/aether/DefaultRepositorySystemSessionFactory.java#L172

Is it feasable to also configure the same User-Agent in bndtools?
Is this the correct place to add the configuration parameter? https://github.com/bndtools/bnd/blob/master/biz.aQute.bnd.maven/src/aQute/bnd/maven/lib/resolve/RemotePostProcessor.java#L96

i suspect it could be maybe here: https://github.com/bndtools/bnd/blob/master/biz.aQute.repository/src/aQute/maven/provider/MavenRemoteRepository.java#L66

Maybe it should belong here https://bnd.bndtools.org/instructions/connection_settings.html
