Change the kubernetes leader election system to use configmaps instead of endpoints. This
allows a simpler migration from Agent5, as Agent6 will not require additional permissions.
Adds in the proc.queue_length and proc.count metrics with the windows version of the Agent.

Add the windows icon to the Infrastructure List for Agents installed on Windows machines.
Fix Docker container --pid=host operations. Previous RCs can cause host system
instabilities and should not be run in pid host mode.
Windows: set correct default value for apm config to enabled, so that the trace agent is
started by default
Removes deprecated process_agent_enabled flag
metrics.yaml is not a "configurable" file - it provides default metrics for
checks and shouldn't be altered. Removed from the GUI configuration file
list.
Windows: gopsutil calls to the CPU module require COM threading model to be
in multi-threaded mode, to guarantee it's safe to make those calls we load
the python checks setting the right COM concurrency mode first. Once loaded
we clear the concurrency mode and python checks that might use COM will set
it as they need.
Windows: make stop/restart of DatadogAgent service stop/restart dependent
services accordingly
Windows: Prevent system tray icon from being displayed more than once
Windows: Make default start behavior of process-agent consistent with Linux Agent
Windows: Fix the item launching the web-based GUI in the systray icon menu
Windows: Process agent service now passes the configuration file argument to the
executable when launching - otherwise service will always come up on
reboots.

Windows: Added developer documentation regarding the caveats of the COM
concurrency model and its implications moving forward. The current state affects
auto-discovery and dynamic scheduling of checks.
