This PR adds a cross-platform PowerShell script that can deploy proxies for Mac / Linux / Windows environments.

Note: I don't have a properly deployed cluster currently, but it's identical to the Linux counterpart found here

Hi @avdaredevil, I later realized the script could be vastly simplified by port-forwarding services directly: #2836.

Can you adjust your script too?

Some discussion:
Is powershell in linux well supported? https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-core-on-linux?view=powershell-7
Can we take other approaches like writing node scripts for this?
In windows, can we use mingw to run these?

Hi @Bobgy, thanks for the insights:

• Is powershell in linux well supported? https://docs...
  • Not all parts of powershell, as in the .NET Core which is not used in this script (since .NET core is a really fundamental part of windows. However this should change with PwShell v7 coming out this year). But for this PR, this is a non-issue
• Can we take other approaches like writing node scripts for this?
  • Definitely, and in fact this would be the preferred way! (this in conjuction with using cross-env in package.json)
• In windows, can we use mingw to run these?
  • Yes, but this is not a good solution, as it requires non-standard installations of Linux build tools to run really trivial scripts. (which do not auto-update, or get patches)

[Bobgy]

sounds like node scripts will be the best option going forward. I will try writing more of it.
