.SYNOPSIS
Enables installing SSH even when your system does not have WOW64 or Chocolatey.
.DESCRIPTION
This script enables installing  SSH even when your system does NOT have:
  [1] Chocolatey installed
  [2] WOW64 installed
  [3] .NET Core (Nano)

The use cases are Server Nano and Server Core without WOW64 installed.

To use barebonesinstaller.ps1, expand the .nupkg that this file is contained in
and then place the \tools folder on the target system.

To push tools folder to Nano use 'Copy-Item -tosession $sessionvariable tools c:\tools -recurse'
.PARAMETER SSHServerFeature
Include SSH Server Feature.
.PARAMETER SSHServerPort
The port that SSHD Server should listen on.
.PARAMETER DeleteServerKeysAfterInstalled
Delete server private keys after they have been secured
.PARAMETER DeleteConfigAndServerKeys
Delete server private keys and configuration upon uninstall.
.PARAMETER Uninstall
Uninstall (default is to install)
.EXAMPLE
.\barebonesinstaller.ps1 -SSHServerFeature
.EXAMPLE
.\barebonesinstaller.ps1 -SSHServerFeature -Uninstall

  2016/09/20 - Modified by DawinJS to:
  - only grab TCP ports so that parsing PID would be reliable (and is sufficient for my purposes)
  - If -GetProcessDetails
    - parse PID
    - use "get-process" to find exe name (netstat -b is not pulling it for my scenario)
    - finds a full process path name in a Nano TP5 compatible way (WMIC)
  - If -ShowProgress - show progress bar - takes a while to grab all exe paths for all processes
  - If -FilterOnPorts - filter results for these ports before grabbing process details
