Some of the enviornment variables or Airlfow configuration we define are essential and we don't want to allow the user to modify them, or others are overridable. This commit support support having both of these, and implement the right precedence to allow the user to override the optional ones, but not the essential.
Additionally, I added a couple of environment variables that are required by MWAA.
