Provide a query syntax for use in oslcquery to say 'find the configuration with this name'

[barny]

This might be used for example to enable commandline querying such as with gc for finding uses of a contribution, which uses a query that embeds the local contribution URL, e.g. for gcm:

• oslc.where=oslc_config:contribution{oslc_config:configuration=<https://jazz.ibm.com:9443/rm/cm/stream/_dNpoIFEfEe2d5dG-54qhbg>}

So there needs to be a way to specify the application (and project/component?) that will be searched for the configuration name, perhaps a prefix like rm: or gc:

And there needs to be syntax to delimit it.

A challenge with this for RM is that there's no way to search globally for configurations so have to open each project and scan all its configurations.
