Feature: flexlogger plugins

[alexluck-sift]

Updates to Sift Client:

• Now both gRPC and REST URLs are required (previously, these were implicit)
• Exposes some additional properties for use in Flexlogger plugins

Adds Flexlogger plugins for:

• Sift Stream - Live streaming of Flexlogger data
• Sift TDMS Uploader - Uploads TDMS files to Sift after recording is complete

On internal VIs:

• Run "Clean Up Diagram" (Ctrl + U) to format
• Add docstrings so they appear when "Show Context Help" is enabled.

Make sure we're checking output errors for all VIs that provide them. Internal functions should also check incoming errors and bypass the function if there is one where it makes sense to do so.

Can you open a ticket to move some of these utilities to Sift Client?
