Use bundletester for amulet test execution

Switch to using bundletester for execution of functional tests,
leveraging tox to build out test virtualenvs.

Rename amulet tests inline with gate-* and dfs-* naming standards.

Update README to refer to functional testing section of the charm
guide.

-This directory provides Amulet tests to verify basic deployment functionality
-from the perspective of this charm, its requirements and its features, as
-exercised in a subset of the full OpenStack deployment test bundle topology.
-
-Reference:  lp:openstack-charm-testing for full test bundles.
-
-A single topology and configuration is defined and deployed, once for each of
-the defined Ubuntu:OpenStack release combos.  The ongoing goal is for this
-charm to always possess tests and combo definitions for all currently-supported
-release combinations of U:OS.
-
-test_* methods are called in lexical sort order, as with most runners.  However,
-each individual test method should be idempotent and expected to pass regardless
-of run order or Ubuntu:OpenStack combo.  When writing or modifying tests,
-ensure that every individual test is not dependent on another test_ method.
-
-Test naming convention, purely for code organization purposes:
-    1xx service and endpoint checks
-    2xx relation checks
-    3xx config checks
-    4xx functional checks
-    9xx restarts, config changes, actions and other final checks
-
-In order to run tests, charm-tools and juju must be installed:
-    sudo add-apt-repository ppa:juju/stable
-    sudo apt-get update
-    sudo apt-get install charm-tools juju juju-deployer amulet
-
-Alternatively, tests may be exercised with proposed or development versions
-of juju and related tools:
-
-    # juju proposed version
-    sudo add-apt-repository ppa:juju/proposed
-    sudo apt-get update
-    sudo apt-get install charm-tools juju juju-deployer
-
-    # juju development version
-    sudo add-apt-repository ppa:juju/devel
-    sudo apt-get update
-    sudo apt-get install charm-tools juju juju-deployer
-
-Some tests may need to download files. If a web proxy server is required in
-the environment, the AMULET_HTTP_PROXY environment variable must be set and
-passed into the juju test command.  This is unrelated to juju's http proxy
-settings or behavior.
-
-The following examples demonstrate different ways that tests can be executed.
-All examples are run from the charm's root directory.
-
-  * To run all +x tests in the tests directory:
-
-      bzr branch lp:charms/trusty/foo
-      cd foo
-      make functional_test
-
-  * To run the tests against a specific release combo as defined in tests/:
-
-      bzr branch lp:charms/trusty/foo
-      cd foo
-      juju test -v -p AMULET_HTTP_PROXY 015-basic-trusty-icehouse
-
-  * To run tests and keep the juju environment deployed after a failure:
-
-      bzr branch lp:charms/trusty/foo
-      cd foo
-      juju test --set-e -v -p AMULET_HTTP_PROXY 015-basic-trusty-icehouse
-
-  * To re-run a test module against an already deployed environment (one
-    that was deployed by a previous call to 'juju test --set-e'):
-
-      ./tests/015-basic-trusty-icehouse
-
-  * Even with --set-e, `juju test` will tear down the deployment when all
-    tests pass. The following work flow may be more effective when
-    iterating on test writing.
-
-      bzr branch lp:charms/trusty/foo
-      cd foo
-      ./tests/setup/00-setup
-      juju bootstrap
-      ./tests/015-basic-trusty-icehouse
-      # make some changes, run tests again
-      ./tests/015-basic-trusty-icehouse
-      # make some changes, run tests again
-      ./tests/015-basic-trusty-icehouse
-
-  * There may be test definitions in the tests/ dir which are not set +x
-    executable.  This is generally true for deprecated releases, or for
-    upcoming releases which are not yet validated and enabled.  To enable
-    and run these tests:
-      bzr branch lp:charms/trusty/foo
-      cd foo
-      ls tests
-      chmod +x tests/017-basic-trusty-kilo
-      ./tests/setup/00-setup
-      juju bootstrap
-      ./tests/017-basic-trusty-kilo
-
-
-Additional notes:
-
-  * Use DEBUG to turn on debug logging, use ERROR otherwise.
-      u = OpenStackAmuletUtils(ERROR)
-      u = OpenStackAmuletUtils(DEBUG)
-
-  * To interact with the deployed environment:
-      export OS_USERNAME=admin
-      export OS_PASSWORD=openstack
-      export OS_TENANT_NAME=admin
-      export OS_REGION_NAME=RegionOne
-      export OS_AUTH_URL=${OS_AUTH_PROTOCOL:-http}://`juju-deployer -e trusty -f keystone`:5000/v2.0
-      keystone user-list
