install_java_plugin is missing overrides argument support

[nick-at-finix]

In https://github.com/killbill/killbill-cloud/commit/fad8cc9c0293bae6a9c7000edb4e55764af2012d, the overrides and -ssl-verify options were moved from the class level to the method level, effectively removing support for these options for install_java_plugin.

>   --overrides url:"https://maven.pkg.github.com/my-companys/killbill-plugins" token:.. \
>   --group-id com.my-company \
>   --artifact-id my-plugin \
>   --destination /var/lib/killbill/bundles \
>   --version 2.3.24
