Devstack stop supporting Tempest deprecated cred options

[Ghanshyam Mann]

Tempest provides three different credential providers for tests:
- dynamic credentials, which is what is used in all gate jobs
- preprovisioned credentials, which is used in experimental and
  periodic jobs, not yet in the gate because of bug 1524717
- legacy credentials, which relies on deprecated configuration
  options, and which is itself deprecated.

More details-
http://docs.openstack.org/developer/tempest/configuration.html#credential-provider-mechanisms

Many projects used deprecated credentials which is now failing on gate job as devstack does not set those cred options in conf.
 - I65b56ff681d6c27094380693c953fbc3664eceb0

Projects either using get_configured_credentials with cred type 'user', 'alt_user' or directly using LegacyCredentialProvider which depends on deprecated options.

Project should use dynamic cred to get right cred as mentioned above.

Manila project requires possibility to use "preconfigured" creds and forced to use workaround setting legacy opts manually: https://review.openstack.org/263664 until bug 1524717 is fixed. Only after this bug gets fixed, Manila can use "proper" way of getting creds in Tempest.

Any of the devstack plugin jobs that are using preconfigured hard-coded credentials should not be running in parallel, they should be running serially otherwise there is a risk of over quota type failures in the tempest tests. This is why we test with tenant isolation in the integrated gate and concurrent test workers.

Matt,

the problem is in impossibility to run several classes using same creds, even serially, with latest tempest and devstack. It is use case of Manila.

    Fix CI Tempest jobs

    After merge of change [1] to devstack project, preconfigured creds for
    Tempest cannot be used anymore. But Manila requires such.
    For the moment, latest Tempest interfaces cannot allow us to use
    preconfigured creds because of bug #1524717.
    So, until this bug fixed, we should workaround Devstack changes and
    set legacy opts explicitly.

    Also, redefine new Nutron option 'dnsmasq_local_resolv' to 'False' value,
    that is 'True' by default and was added in change [2].
    Default value causes Nova operations initiated by Manila be very slow.
    That leads to breakage of CI.

    Updated dynamic credential support for funtional test.

    Now devstack does not setup the deprecated configured cred on Tempest
    which is being used here. - https://review.openstack.org/#/c/256164/

    get_configured_credential use the deprecated cred and these tests use
    that for initiating Manager.

For Manila, the Launchpad bug that was referenced above was fixed in December of last year. We need to make sure to finish this up as we do our Tempest updates in the Queens cycle.
