Add remoteSearch boolean query param for supporting GAVC search for Virtual and Remote Repositories

[yuvalojfrog]

Add a support of the new query param for GAVC search for Virtual and Remote Repositories.
remoteSearch is a Boolean param that indicates if the GAVC search goes to virtual/remote repositories.
there is already support of searching by groupId, artifactId, version and classifier and now remoteSearch also should be added.
