Provide a bash completion on host name, module name and options for ansible.

1. Get the ansible-completion.bash file.

2. Copy/move the ansible-completion.bash in your bash_completion.d folder (/etc/bash_completion.d, /usr/local/etc/bash_completion.dor ~/bash_completion.d).

3. Or copy/move it where you want and then load the ansible-completion.bash file in your ~/.bashrc or ~/.profile like that:

   source ~/ansible-completion.bash
   

4. Reload your shell with something like source ~/.bashrc or source ~/.profile

1. Clone the repo, install bash an auto-completion2 with homebew: brew install bash bash-completion2

2. Change your terminal bash to a homebrew one by setting the command option to /usr/local/bin/bash

3. Add the following code to your ~/.profile:

   if [ -f $(brew --prefix)/share/bash-completion/bash_completion ]; then
     . $(brew --prefix)/share/bash-completion/bash_completion
   fi
   

4. Create a symbolik link for ansible-completion.bash:

ln -vs ~/soft/ansible-completion/ansible-completion.bash /usr/local/share/bash-completion/completions/ansible
   ```

Good to know
------------
If the `--module-path` (`-M`) or `--inventory-file` (`-i`) is on the command line, the completion will use it.

For the completion on module name, the completion script build a cache of modules names.<br />
You can set the cache timeout with the environement variable `ANSIBLE_COMPLETION_CACHE_TIMEOUT`, the default value is `120` secondes.
