Include a Maven specific command to search gavc

[stmosher27]

Currently, needing to search for a Maven artifact via the Maven coordinates requires parsing to search for these artifacts with the basic search i.e. jf rt search "com/test/testArtifact1.10**jar"

The ability to run a specific command like jf rt sg (search gavc) com.test:testArtifact:pom:1.10 would be nice as these are the coordinates Maven provides and would require no parsing

There is a REST API to search gavc, but this still will not just take the native maven coordinates and still requires parsing
