Container setup for TEM workflow + tomography/SPA bugfixes

[tieneupin]

This PR sets up the Helm charts needed in order to create an instrument server container to test the TEM workflow with. Along the way, various bugs that were uncovered were also patched:

• Added an rsync_url key to the MurfeyInstanceEnvironment class, now that we are supporting externally run rsync daemons
• Set microscope name using instrument_name from database lookup, instead of using the get_microscope() function
• Added logs to the prepare_(eer_)gain() function to see why the subprocess fails
• Fixed logic for why the first tomography position is not processed
• Added logic to handle cases in the feedback_callback function where no workflows are found
• Locked NumPy to <2 (NumPy compatibility will need to be addressed in future; see Fix use of NumPy in Murfey repo so that it works with both v1 and v2 #508 )
