Feature Request: Add application client configuration

[bpaskin]

Currently the maven plugin supports setting up and testing with a Liberty App Server, but the configuration does not have the ability to configure and run an application client.

Maybe something like this:

  <clientName>EJbTest</clientName>
  <runtimeArtifact>
      <groupId>io.openliberty</groupId>
      <artifactId>openliberty-runtime</artifactId>
      <version>25.0.0.12</version>
      <type>zip</type>
  </runtimeArtifact>
</configuration>

and then have the client.xml under liberty/config/client.xml

Otherwise, we need to compile and setup our client outside of the dev environment (wlp/bin/client create EJbTest, wlp/bin/client run EJbTest).
