The aexpect module is used by the Docker plugin.  Since we do not
package those separately, let's add it as a global Avocado dependency.

Managing different requirements files for different python version
requires much more efforts when the requirements became too complex.

This issue emerged when a required package `stevedore` decide not
supporting Python 2.6 since version `1.11.0`.

```
>>> import stevedore
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/stevedore/__init__.py", line 23, in <module>
    LOG.addHandler(logging.NullHandler())
AttributeError: 'module' object has no attribute 'NullHandler
```

Pip provides a feature named [Environment
Markers](https://www.python.org/dev/peps/pep-0496/) for requirements
file to include specific packages conditionally which could properly
solve this issue.

This fix:
1. Use environment markers and merge python version specific
requirements files;
2. Remove python version specific requirements files references in
`Makefile` and Travis configuration;
3. Use `pip install -r requirements.txt` to replace per-line package
installation;
4. Restrain package `stevedore` on Python 2.6 to `1.10.0`.

The initial idea about the avocado.restclient namespace was that
eventually users could write scripts using that as an API to
interact with avocado-server using Python code.

While the idea is still valid, the avocado-server interface is
a simple and standards compliant RESTful interface. Thus, users
can still easily interact with it without us having to support
a formal Python API at this point.

In the future, if need arises, we can improve the Python REST
client API and promote it to a public namespace.

Move avocado.plugins to avocado.core.plugins, in conformance to our
purpose of keeping things not related to test developers,
inside avocado.core, isolated from users.

Document requirements.txt, split it into 3 files:

 * requirements.txt - Used to install deps for functionality
 * tests-requirements.txt - Used to install deps to test avocado
 * travis-requirements.txt - Used exclusively for Travis CI jobs

Also, clean up and simplify Travis install job section.
