Clean up imports across the board in tp-qemu. The criteria
followed was:

1) Remove unnecessary imports
2) Turn multi imports from a single entry point to one
   import per line. This increases both patch and
   source code readability.
3) Separate blocks of imports with a line:
   * Python standard library imports
   * Autotest imports
   * virttest imports
   * Internal tp-qemu imports
4) Remove try/except blocks refering autotest libs and
   stick with the virttest.staging copy

This paves the way for the future removal of autotest
references, replacing those references with avocado ones.

'virttest.aexpect' was refactored and turned to its own project.
Let's update all the references to simply 'aexpect'

Correct the type of shared_mem in script. And enlarge the guest_script_overhead
in cfg file to ignore the memory leak lead in guest which will lead to the memory
allocate speed slow and make case failed in the memory allocate step.

Quit ksm_overcommit_guest and turn on swap after test otherwise following
cases using this vm may failed because out of memory.

Also fix a small mistake in test steps.

There's no need to have the name of the "run_<name>" method (main
test entry point) depend on the test name. So, for simplicity sake,
let's just name the test entry point "run".

I have decided to not fallback gracefully to the previous naming
convention as I believe this can lead to confusion in the future.

Make virt-test to have a docstring style mostly compliant with
the sphinx's [1] format, reStructured text. This means that
we have to trade all '@' tags to be ':', mostly.

With the help of the PEP8 script, a semi-automated clean
of the code base was made, and effectively changing some
of the coding style rules of our code base:

 * No more 2 lines spacing among functions
 * No more combined module imports

In the end, it was going to be too difficult to take
into consideration E501 (line length > 80) errors and
W601 (.has_key() is deprecated), so these were ignored,
at least for now.

This class will setup and clean KSM config in different hosts.
You can use setup_ksm to configure it. There are several params
that can be used for ksm configure:

ksm_pages_to_scan: pages ksmd will scan in one loop
ksm_sleep_ms: million secs ksmd will sleep between two scan
ksm_run: start ksmd or not
ksm_module: if ksm is not compiled into kerenl need this parameter
            tell scripts which module should it load
disable_ksmtuned: if we need idsable ksmtuned during our test

This class also can be used to disable KSM in some special case with
set setup_ksm to yes and ksm_run to 0 or no.

Add three KSM test:
    - Negative test for ksm
    - KSM per vm
    - Merging and Splitting in one vm

All this three test needs the following steps:
1. Get and set the env parameters for KSM
2. Boot up guest with proper command line
3. Set env inside of guest
4. Allocate 0 pages to make the KSM run
5. Allocate different pages to get split of the pages(option for
   different cases)
6. Result check and env reset

change from v1:
    - add the host depended parameters in cfg file
    - use os.system to restart ksmtund as commands will wait the
      return value.
