Prior to openssh 6.4, ssh-keygen -F returned 0 (and no output) when no
host was found. After then, it instead returned 1 and no output. This
revised code behaves correctly with either behaviour. There is
currently no other code path that results in exit(1) and no output.
- removed functions from main scope
- renamed rebalance function to disambiguate from variable
- updated docs with defaults
- added exception handling to command execution
Occasionally, `lvcreate` will prompt on stdin for confirmation. In
particular, this may happen when the volume is being created close to
the location on disk where another volume existed previously. When this
happens, Ansible will hang indefinitely with no indication of the
problem. To work prevent this problem, the `--yes` command-line argument
can be passed to `lvcreate`, which will instruct it not to prompt.

- Changes are no longer erroneously reported on RHEL (#12)
- Adding new link groups on Debian works again.
- This was broken in a previous commit by assuming the OS was RHEL
if `update-alternatives --query <name>` had a return code of 2
- Prefer `--display` over `--query` for determining available
alternatives
- --display is more distro-agnostic and simplifies the code
- Fix missing `msg=` in `fail_json` call when `link` is missing
- Document that `link` is required on RHEL-based distros
Tested on Ubuntu 12.04+ and CentOS 6/7
These are all the code changes from Brian's review:
* change #! line
* rename "host" to "name" [keep as alias]
* make documentation clearer
* imports 1 per line
* use get_bin_path to find ssh-keygen
* key not actually required when removing host
The known_hosts module lets you add or remove a host from the
known_hosts file. This is useful if you're going to want to use the
git module over ssh, for example. If you have a very large number of
host keys to manage, you will find the template module more useful.
This was pull request 7840 from the old ansible repo, which was
accepted-in-principle but not yet merged. The mailing list thread
reading it is:

The function normalizes checks for UTF-8, but the same issue exists for
other locales as well. This fix adds normalization for EUC-JP, a Japanese
locale.
