Refs: #3867

Commands affected: server_create/start/shutdown/reboot

Also, the wait functionality is now encapsulated in a _server_wait class
The server_wait command is just an implementation of this class.

Use kamaki.clients.astakos.AstakosClient as a cached astakos client to get
user information and, most importantly, endpoints. Allow users to authenticate
multiple tokens on the same session. In every session there must be at most
one authentication per user/token.

Major change: top kamaki.cli.commands class now contains a base_auth field
with the cached authenticating client. All urls are drained from this field.

Apply the feature wherever is applicable
Generalize the feature by moving the corresponding code to _command_init

This caused warnings about preset variables

Unsolved bug: redudant info in logfile

Kamaki logger module is now available to both cli and clients packages
Users may set the log_file option in configuration file
   kamaki config set log_file ...

Support #3441

This is implemented as a configuration option in cli
Developers may set it as kamaki.clients.Client.MAX_THREADS = <limit>

Adjust documentation acoordingly

Feature #3546

to avoid kamaki failures due to logging problems

- LOG_TOKEN: whether to log user token in http requests (default: off)
- LOG_DATA: whether to log http body (send or secv - default: off)

config options: log_token=off, log_data=off

Suggested use:
- declare:
    (self.)arguments = dict(argname=Argument())
- set/update:
    self['argname'] = Argument(...)
- use:
    self['argname']
- get arg object:
    self.get_argument_object('argname')

Not __getitem__ of cli.commands does return arg.value
- to set:
 mycmd['argname'] = Argument(…)
or
 mycmd.argument['argname'] = Argument(…)
- to get Argument object:
 mycmd.get_argument_object('argname')
or
 mycmd.argument['argname']
- to get Argument value:
 mycmd['argname']
or
 mycmd['argname'].get_argument('argname') //bw comp.

Now any cli.commands subclass instance:
- sets args like this:
 mycmd['myargname'] = Argument()
instead of
 mycmd.arguments['myargname']
- gets args like this:
 mycmd['myargname'] = Argument()
instead of
 mycmd.arguments['myargname']
-get argument values like this:
 mycmd['myargname'].value
instead of
 mycmd.get_argument('myargname')
Backwards compatibility is preserved -old methds still ok

pithos_sh download is incremental, therefore better than kamaki download
