Make output from check_logs less verbose

This commit changes the output of check_logs.py to be a bit more
concise and clear. Instead of printing out every instance of errors
found in the log files it will only print out which individual files
had errors. If a file is marked as not allowing ERRORS or TRACES it
also prints that along with the filename. This should hopefully avoid
confusion around the operation of this script running in the gate.

Fix unstable assertion in test_cinder_endpoints

In simple_read_only.test_cinder.test_cinder_endpoints, the test case
assumes that the first table of 'cinder endpoints' always ['nova',
'Value']. However, it is sometimes wrong.
So in this commit, the test verifies that they have 2 or more headers
and has a 'Value' header.

Make SwiftScenarioTest methods public

An earlier refactoring (commit
0d49411dbb7d6818bb6ca82ba5b769eeffd8f305) extracted the test manager
to a new class. In order to limit the surface area of the change
existing methods name were left unchanged.

This change updates those method names to make them explicitly
public so future test developers recognize their availability.

Add a test for deleting multiple objects by POST method

From swift Icehouse version, bulk deletion supports POST method as well as
DELETE.

Extra fixes:
 - Bulk is an optional function with WSGI middleware, therefore each test
   is annotated with @test.requires_ext
 - Refactor test_account_bulk.py by separating common codes to one method
 - Simplify delete_account method of the Swift's account service client

Partially implements blueprint add-icehouse-swift-tests

Backward compatibility to credentials in conf

Before switching to the YAML based configuration as the default for
credentials, we need to introduce backward compatibility to allow
credentials to be configured in tempest.conf.

Add response schema for V2 sec grp default rule

This patch adds response schema for nova V2
'os-security-group-default-rules' APIs.

Response body of create/show 'os-security-group-default-rules' -
{
    "security_group_default_rule": {
        "from_port": 80,
        "id": 1,
        "ip_protocol": "TCP",
        "ip_range":{
            "cidr": "10.10.10.0/24"
        },
        "to_port": 80
    }
}

Response body of list 'os-security-group-default-rules' -
{
    "security_group_default_rules": [
        {
            "from_port": 80,
            "id": 1,
            "ip_protocol": "TCP",
            "ip_range": {
                "cidr": "10.10.10.0/24"
            },
            "to_port": 80
        }
    ]
}

Delete API only returns 204 status code.

Fix scenarios not passing down specific network

Nova v2 api expects nics in specific networks to be passed
down in an array of "networks". nics is used in novaclient
but converted to networks in
python-novaclient/tree/novaclient/v1_1/servers.py#n520

Apply the conversion to the parameters to make the check
pass in case where there would be multiple networks
matching the requirements. Also remove a case where scenario
manager forced in the wrong network into the tests.

Removes bogus negative create image compute

Removes test_create_image_specify_multibyte_character_image_name
as it is not a valid test. It currently does not send an
invalid utf-8 sequence, but a valid unicode one. Also we can't actually
send an invalid utf-8 sequence via JSON as it is not possible to
encode an invalid UTF-8 sequence into a series of unicode characters
which is what JSON uses as strings. So its not possible for it
to fail this way. And we don't do XML testing for this type of test.
