<#
.SYNOPSIS
   Exports command as JSON for icinga director

.DESCRIPTION
   Get-IcingaCheckCommandConfig returns a JSON-file of one or all 'Invoke-IcingaCheck'-Commands, which can be imported via Icinga-Director
   When no single command is specified all commands will be exported, and vice versa.

   More Information on https://github.com/Icinga/icinga-powershell-framework

.FUNCTIONALITY
   This module is intended to be used to export one or all PowerShell-Modules with the namespace 'Invoke-IcingaCheck'.
   The JSON-Export, which will be generated through this module is structured like an Icinga-Director-JSON-Export, so it can be imported via the Icinga-Director the same way.

.EXAMPLE
   PS>Get-IcingaCheckCommandConfig
   Check Command JSON for the following commands:
   - 'Invoke-IcingaCheckBiosSerial'
   - 'Invoke-IcingaCheckCPU'
   - 'Invoke-IcingaCheckProcessCount'
   - 'Invoke-IcingaCheckService'
   - 'Invoke-IcingaCheckUpdates'
   - 'Invoke-IcingaCheckUptime'
   - 'Invoke-IcingaCheckUsedPartitionSpace'
   - 'Invoke-IcingaCheckUsers'
############################################################

.EXAMPLE
   Get-IcingaCheckCommandConfig -OutDirectory 'C:\Users\icinga\config-exports'
   The following commands were exported:
   - 'Invoke-IcingaCheckBiosSerial'
   - 'Invoke-IcingaCheckCPU'
   - 'Invoke-IcingaCheckProcessCount'
   - 'Invoke-IcingaCheckService'
   - 'Invoke-IcingaCheckUpdates'
   - 'Invoke-IcingaCheckUptime'
   - 'Invoke-IcingaCheckUsedPartitionSpace'
   - 'Invoke-IcingaCheckUsers'
   JSON export created in 'C:\Users\icinga\config-exports\PowerShell_CheckCommands_09-13-2019-10-55-1989.json'

.EXAMPLE
   Get-IcingaCheckCommandConfig Invoke-IcingaCheckBiosSerial, Invoke-IcingaCheckCPU -OutDirectory 'C:\Users\icinga\config-exports'
   The following commands were exported:
   - 'Invoke-IcingaCheckBiosSerial'
   - 'Invoke-IcingaCheckCPU'
   JSON export created in 'C:\Users\icinga\config-exports\PowerShell_CheckCommands_09-13-2019-10-58-5342.json'

.PARAMETER CheckName
   Used to specify an array of commands which should be exported.
   Separated with ','

.PARAMETER FileName
   Define a custom file name for the exported `.json`/`.conf` file

.PARAMETER IcingaConfig
   Will switch the configuration generator to write plain Icinga 2 `.conf`
   files instead of Icinga Director Basket `.json` files

.INPUTS
   System.Array

.OUTPUTS
   System.String
