 * Run Program
 * @function $os~runProgram
 * @param {string} program - Program to execute
 * @param {string|string[]} arguments - Arguments. It can be either a string or an arry containing them
 * @param {RunProgramOptions} [options]
 * @param {boolean} [options.runInBackground=false] - Run the command in the background
 * @param {boolean} [options.retrieveStdStreams=false] - Returns a hash describing the process stdout, stderr and
 * exit code
 * @param {boolean} [options.detachStdStreams=false] - Save standard streams to temporary files while executing
 * the program (solves some processes hanging because of unclosed streams)
 * @param {string} [options.runAs=null] - User used to run the program as. Only when running as admin
 * @param {string} [options.cwd] - Working directory
 * @param {Object} [options.env={}] - Object containing extra environment variables to be made accesible to the running
 * process
 * @param {string} [options.input=null] - Value passed as stdin to the spawned process
 * @param {Object} [options.logger=null] - If not provided the global package logger will be used
 *
 * @example
 * // returns "Hello World"
 * runProgram('echo', 'Hello World')
 * @example <caption>Pass arguments as array</caption>
 * // returns mysql databases
 * runProgram('mysql', ['-uroot', '-pbitnami', '-e', 'show databases'], {runAs: 'mysql'});
