Creates bash completion file.
Creates a bash completion file at the specified path.
Note: Bash completions will only work with the prefix with which the script is created (e.g. ./vcli or vcli).
Once created, the file has to be moved to the bash completion script folder - usually /etc/bash_completion.d/.
