Decoupled download and copy on target host

New architecture design with download performed on "localhost" and execution on target nodes.
This approach allows you to download once, execute many, saving time and bandwidth.
Code is default executed on "/opt" to avoid some 'noexec' on "/tmp" enterprise setup.
Customizable GPG key server variable "gpg_server".
Updated documentation and execution.

Improved code and doc

• add the full dependency list: unzip, gpg, dirmngr, file
• improved code with Ansible best practices (command instead of shelll, code folding, etc.)
• improved documentation with full variable description

First release

Code is stable and passed all CI quality tests
