//! Upload a Modoule to remote host and call it with data.
//!
//! A module is an executable, that accepts structured
//! data as Input (json) via stdin and performs
//! actions based on the provided data.
//!
//! The Module optionally takes default data from <DATA_FILE_PATH>
//! these get overwritten with custom values in
//! host var host.vars.module_<module_name>
//! <DATA_FILE_PATH> should contain all information of the
//! expected data structure
//!
//! Usage:
//!
//! ```shell
//! $ tricorder -i inventory module --data <DATA_FILE_PATH> --module <MODULE_PATH>
//! $ tricorder -i inventory module --module <MODULE_PATH>
//! ```
//!
