utils module is too big - break it up

[clayg]

At last count, the swift.common.utils module is 7K lines

https://github.com/openstack/swift/blob/master/swift/common/utils.py

We want to break it up further to swift.common.utils.X

Where some examples of related utils functions/classes that might make their own module are

    - swift.common.utils.logging
    - swift.common.utils.sharding (stuff to do with shard ranges / sharding)
    - swift.common.utils.config (stuff to do with config parsing)

N.B. It might make sense to move some stuff out to existing common modules e.g. swift.common.request_helpers rather than create a new swift.common.utils.request_helpers

The most difficult part of the refactor will be avoiding circular dependencies, but that should be easily detectable (ImportError). It may be tempting to move some existing common modules under utils, or some new utils.X modules out to common.X, but we can do that more easily after we split up utils, so we should try to wait.
