This commit removes the commons codec dependency and simplifies the
hasher code by only supporting bcrypt encryption in the users file. All tests
now also exercise the esusers realm with bcrypt instead of plain text passwords.

Original commit: elastic/x-pack-elasticsearch@3119267851
This commit is a squashed commit of work done in conjunction with @rmuir to make
shield work properly with elasticsearch 2.0. This includes ensuring all tests
pass when running with the security manager and updating the code to be compatible
with the latest core forbidden apis.
Shield is now a child project of elasticsearch-parent and inherits a lot of common
build, test, and static coverage functionality from that project resulting in a much
smaller and simpler pom.xml for shield. As part of this work, Shield can now read
rest tests from the elasticsearch jar so the rest tests are run automatically when
running the slow tests.
