Event Store Option Documentation Generation

1. Create a tool that will generate the options documentation (preferably in Markdown)
    - The tool will need an argument that will point it to the event store binary paths (single node, cluster node). The paths are needed to inspect the executables for the options.
2. Create the necessary scripts that will be used either from powershell or bash to call the new tool with the needed arguments

PS: NOT READY FOR MERGING
And if it must be NDesk, not from Nuget :-)
