add local windows event log source

[rjury-sumo]

This PR adds support for a local windows events source for the installed collector. Like the local file source this is a special case as it can only be applied to existing installed collectors rather than to a hosted collector.

I don't have tests for this (the local file source doesn't either) - but have successfully been able to create or modify sources on a windows instance with installed collector installed using the two example configurations in the mardkdown file.

This was requested by one sumo customer and has an internal JIRA field request https://sumologic.atlassian.net/browse/FIELD-95

Closes #581

thanks @rjury-sumo for creating the PR. LGTM except one point

[vsinghal13]

can we get the allow_list also added?

[rjury-sumo]

I've done that, tidied up a few loose ends and fixed the two linting bugs

If you do want to test it works fine with this tf if you have an installed collector

terraform {
  required_providers {
    sumologic = {
      source = "sumologic.com/dev/sumologic"
      version = "~> 1.0.0"
    }
  }
}

data "sumologic_collector" "installed_collector" {
  name = "terraform_source_testing"
}

resource "sumologic_local_windows_event_log_source" "local" {
  name             = "windows_logs"
  description      = "windows system and application logs in json format"
  category         = "/os/windows/events"
  collector_id     = "${data.sumologic_collector.installed_collector.id}"
  log_names  = ["System","Application","Microsoft-Windows-PowerShell/Operational", "Microsoft-Windows-TaskScheduler/Operational"]
  deny_list = "9999,7890"
 // allow_list = "1000,2000"
  event_format = 1 // 0 = XML, 1 = JSON
}

Vijit Singhal asked me to create this as a new PR on the repo so will close this out. Closed in favour of #785
