* In order to check if something went wrong while running the various pip commands using the command module, we need to know, at least, the return code, this way we can report the failure.
* `salt.modules.pip.uninstall()` now returns the `cmd.run_all` `dict` instead of a list of strings. **This breaks previous behaviour**.
* Added a test case for `salt.modules.pip.uninstall()` changes.
* Moved the state `pip.installed` tests to it's own module, the correct one.
* Added a test which checks for the presence of errors while running `pip.installed` introduced while fixing #2028
* `salt.states.pip.installed()` now keeps a reference to the output of the `__salt__['pip.install']()` call. The reason for this is that we need to know and pass along any information about an eventual error when running that call. This is now done in addition to the old behaviour.
* Add some tests which triggered the issue.
* Test both master and minion events firing
* Allow targeting the minions in `tests.integration.ModuleCase.run_function()`
* The above item allows to also test events firing using `tcp` as `ipc_mode` which is being used by the tests `sub_minion`
* `salt.modules.file.contains()`, `salt.modules.file.contains_regex()`, `salt.modules.file.contains_glob()` and `salt.utils.find` now do the searching/matching against chunks of data; using defaults, 32KB chunks of data in files; instead of searching/matching line by line.
* Based on the above changes `salt.states.file.append()`, when checking if the text to append is already present, now uses `salt.modules.file.contains_regex()` in order to match spanning multiple lines ignoring the addition/deletion of white-space or new lines, except inside commas.
* The regex used on the above item is built at runtime using `salt.utils.build_whitepace_splited_regex()`, just feed the text to it and you'll get back the proper regex to the matching/searching on, for example `salt.modules.file.contains_regex()`.
* Added tests for all this code.
Corey Quinn reported a issue where __grains__['os_family'] returned a
KeyError. This commits adds a check to the grains module test to ensure
os_family is present.
Defined "integration.run_tests()" function which can be used to execute
a particular integration test case. Existing bolerplate code in modules
and states tests is replaced with following lines:
if __name__ == '__main__':
from integration import run_tests
run_tests(TestCaseName)
Typical usecase could look like this:
python integration/modules/pip.py --no-clean -vv
I don't really like doing this, but `/tmp/subsalttest dir` is already
hardcoded in other places for running tests.
Without this, when running tests under a mounted Vagrant drive,
`ssh-keygen` doesn't have permission to create the symlink for
known_hosts to known_hosts.old, causing a test to fail.
```

FAIL: test_rm_known_host (integration.modules.ssh.SSHModuleTest)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/vagrant/tests/integration/modules/ssh.py", line 143, in

AssertionError: 'exists' != 'add'

In addition to traditional file system path test discovery it is
useful to run a test by stating it's dotted python path. For example,
this will only run the cmdmod integration tests from the
module suite::
$ runtests.py -n tests.integration.modules.cmdmod
This caused problems when adding another host and you'd end up with
entries such as:
```
192.168.1.2\t\thost2\thost2alias192.168.1.1\t\thost1\thost1alias
```
Test updated to reflect.
Given a state entry like the following:
```
host-staging-web:
host:
- present
- ip: 10.102.130.100
- names:
- staging-web.fqdn.com
- staging-web
- alt-staging-hostname
```
You'd end up with three different entries in your hosts file:
```
10.102.130.100 staging-web.fqdn.com
10.102.130.100 staging-web.fqdn.com staging-web
10.102.130.100 staging-web.fqdn.com staging-web alt-staging-hostname
```
This corrects it by removing the previous line before appending the
newly crafted on, and adds tests to prove it.
Integration tests requiring a salt master and daemon were seperated
from pure unit tests. For now both are run with runtest.py. In
the future it could take arguments for which type of tests to run.
