Fixing Windows CORE Issue

[JeffAshton]

Switching from github.com/lxn/win to github.com/JeffAshton/win_pdh. This is a fork of the original library, but containing only the performance counters wrappers.

thanks @JeffAshton, can you change docs/LICENSE_OF_DEPENDENCIES as well?

[JeffAshton]

@sparrc : Docs have been updated Cameron. Thanks for Telegraf. :)

[sparrc]

No problem, I looked into your fork and noticed that it only represents ~400 lines of code. Could you actually just copy and paste that code directly here into a file within the same package as the plugin? For a dependency that small I prefer to just have it in-repo.

You can keep the license of the code the same, and paste it in here as well if you want.

[JeffAshton]

Hey @sparrc, I brought in the pdh library and appended the license and authors. I think that should cover us legally.

[JeffAshton]

@sparrc, Is there anything else you need from me on this one?

[sparrc]

Sorry for leaving this hanging for a while. Looks like it needs to be rebased and then I can merge for 1.2.

[JeffAshton]

Hey @sparrc , I've rebased the changes. Not sure why a CI build didn't kick off. Can you kick one off for me? Thanks

[sparrc]

we had a configuration issue with CircleCI that had builds from forks disabled. I've created a separate PR (#2180) to merge this change and close #1763
