Prefer categorized modules to uncategorized, such that if someone does an install on top of old content
the categorized modules will win over the 1.1 uncategorized modules, as the packages may not automatically
clean up the old content.

Excplicity set paramiko's logging level to WARNING.
By default it inherits ansible's DEBUG logging level (set in
callbacks.py) and fills the log file with useless debug messages.
Obviously it only applies if log_path is set in ansible.cfg

pip module blowing up when name is not included in arg list

This code:
```
    if name.endswith('.tar.gz') or name.endswith('.tar.bz2') or
name.endswith('.zip'):
        is_tar = True
```
was not checking whether name is defined since it is an
optional param.

**Summary**:

There was a bug in the previous commit; pip module would add --use-mirrors options to a source package when state is absent. The bug is resolved in this commit by checking ``not is_package`` in the if branch.

Furthermore, in order to support non-vcs source name like tarballs, we must not add -e option to the arg list. Given this circumstance, this commit have is_tar and is_vcs and the latter is checked to add -e option. Since mirrors do not make sense with vcs or tarball source, this commit will not add --use-mirrors (default to True) as always.
