Removing helpful file for testing :(

Removing the jetty zip file as a help for travis tests. The zip file was
too big for Github's API
Updating steps & docs for running tests
Updating CurateND to new SOLR schema

* All tests are passing locally

* Adding maintenance:reindex_solr cap task
    With updates to the SOLR schema, we need to reindex the existing
    Fedora objects.

* Removing solr txt files for new schema
    The new schema does not use these (for better or worse)
Updating Sufia models usage

Cleaning up, I hope, the RMagick dependency.
Attempting least invasive rmagick removal
Pointing to sufia-models instead of sufia
Adding psych dependency
Locking to specific psych version
Updating to psych patched ActiveFedora
Updating sufia
Updating active-fedora to project hydra
Updating jenkins to behave like pre-production

Note, this should cause a build fail. Then I can proceed with fixing it.
Create LdapService class to query LDAP service.
