Change plugin name and depend on 2.4

As we get closer to releasing this plugin to work with 2.4, we should
update the name -- going with search-processor -- to better reflect the
idea that it will be able to transform search requests and responses.
Also, we need to update the build to point to 2.4 snapshots, instead of
2.1.
