Do not use obsolete modules from oslo-incubator

[Nikhil Manchanda]

There are quite a few modules that are in use in Trove today that were in the past taken from oslo-incubator, but which have now been graduated to their own libraries -- obsoleting them from oslo-incubator.

Trove still uses a few of these modules. We need to go through them and ensure that we are using the current modules from the oslo libs, and not the obsolete code from the oslo-incubator modules.

The specific modules in question are:
openstack/trove: exception
openstack/trove: excutils
openstack/trove: gettextutils
openstack/trove: importutils
openstack/trove: iniparser
openstack/trove: jsonutils
openstack/trove: network_utils
openstack/trove: notifier
openstack/trove: pastedeploy
openstack/trove: rpc
openstack/trove: strutils
openstack/trove: testutils
openstack/trove: timeutils
openstack/trove: utils
openstack/trove: wsgi

[Denis M. (dmakogon)]

"network_utils" module is a dependency of kombu implementation of RPC backend.
see https://github.com/openstack/trove/search?utf8=%E2%9C%93&q=network_utils&type=Code

[Denis M. (dmakogon)]

"testutils" module can be dropped off because it's not used anywhere
see https://github.com/openstack/trove/search?utf8=%E2%9C%93&q=testutils&type=Code

I'm working in a proximate area anyway so I'm assigning this to myself.

[Denis M. (dmakogon)]

Amrith, we might split this task, same as we did with logging.

    Obsolete oslo-incubator modules - unused modules

    This change is part of a multi-part change set to handle obsolete and
    graduated oslo modules.

    This commit handles obsolete oslo-incubator modules that are not used
    in Trove but are referenced in openstack-common.conf

    The change here is to remove them from openstack-common.conf and
    delete them from trove/openstack/common.

    While excutils, network_utils and strutils are deleted from
    openstack-common.conf the files are retained because of dependencies
    within oslo-incubator.

    Obsolete oslo-incubator modules - timeutils

    This change is part of a multi-part change set to handle obsolete and

    This commit handles the timeutils module.

    The change here is to remove it from openstack-common.conf and point

    Obsolete oslo-incubator modules - exception

    This change is part of a multi-part change set to handle obsolete and
    graduated oslo modules. This change relates to the exception module
    that is now obsolete. The change here is to delete the file from
    openstack-common.conf and handle the change as it ripples into the
    modules that used to include exception.

    The change is modeled on the change that was implemented in
    oslo-incubator when this module was deprecated. See review
    https://review.openstack.org/#/c/39314

    wsgi.py will be deprecated in another change so the only change being
    made here is (effectively) to extensions.py

    We can't delete the file in openstack/common because there is still a
    dependency within oslo-incubator.

    Obsolete oslo-incubator modules - wsgi

    This change is part of a multi-part change set to handle obsolete and
    graduated oslo modules. This commit handles the wsgi module. The way
    in which other projects appear to have handled this situation is to
    copy the wsgi module into the project. See, for example,
    https://review.openstack.org/#/c/129260/

    I've done the same thing, and since we already have a wsgi module in
    trove/common, I've called the newly imported module base_wsgi.py and
    renamed the imports accordingly.

    In the fullness of time, we could consider merging wsgi.py and
    base_wsgi.py

    However since there are internal dependencies between
    middleware/context.py and wsgi.py (within oslo-incubator) I can't
    delete or modify those files.

    Obsolete oslo-incubator modules - processutils

    This change is part of a multi-part change set to handle obsolete and
    graduated oslo modules. This commit handles the processutils module
    which is now oslo.concurrency (oslo_concurrency). The change here is
    to remove it from openstack-common.conf and add oslo.concurrency to
    requirements.txt. Since nothing in oslo-incubator depends on
    processutils, the module is also deleted from the oslo-incubator
    imports.

    Eliminate redundant modules from oslo-incubator

    This change is part of a multi-part change set to handle obsolete and
    graduated oslo modules. This commit cleans up openstack-common.conf
    which has unnecessary entries for middleware and fileutils that are
    not required in trove.

    Also, trove acquired a trove/openstack/common/utils.py which had two
    routines that were long ago moved into strutils (now oslo.utils). The
    sole remaining reference to that source file has been updated to
    reflect this.
