Major re-work of correlator M&C interface

[bhazelton]

Description

Add the following tables:

• array_signal_source: Array-wide information about the commanded signal source

  • time* (GPS second): time when the input source was changed
  • source (string): One of "antenna", "load", "noise", "digital_same_seed", "digital_different_seed"

• correlator_component_event_time: When correlator components had an event (related to normal observing)

  • component_event* (string): One of "f_engine_sync", "x_engine_integration" (in this case it's calculated from the Mcount, "catcher_start", "catcher_stop". (Note: "x_engine_integration" is not yet supported because the value for it is not in redis yet).
  • time* (GPS second): start time for this component (Note: a float, not an int)

Remove the following tables:

• correlator_control_state
• correlator_control_command
• correlator_take_data_arguments
• correlator_config_command

Motivation and Context

First part of work outlined in #606, covering the tables that have the required info in redis now.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• Schema change (any change to the SQL tables)
• New feature without schema change (non-breaking change which adds functionality)
• Change associated with a change in redis structure
• Breaking change (fix or feature that would cause existing functionality to change)
• Version change
• Build or continuous integration change
• Other

Checklist:

Schema change:

• My code follows the code style of this project.
• I have added or updated the docstrings associated with my feature using the numpy docstring format.
• I have created an alembic version file to produce the schema change.
• I have tested looping upgrading and downgrading the alembic version and tests pass consistently.
• I understand the updates required onsite (detailed in the readme) and I will make those
  changes when this is merged.
• I have updated the schema documentation document with my changes (under docs/mc_definition.tex)
• I have added tests to cover my new feature.
• Unit tests pass on site (This is a critical check, CI can differ from site).
• I have updated the CHANGELOG.

Breaking change checklist:

• My code follows the code style of this project.
• I have updated the docstrings associated with my change using the numpy docstring format.
• I have detailed any changes required to other HERA repos above and I will coordinate
  implementing the changes across all the repos.
• I understand the updates required onsite (detailed in the readme) and I will make those
  changes when this is merged.
• I have added tests to cover my changes.
• Unit tests pass on site (This is a critical check, CI can differ from site).
• I have updated the CHANGELOG.

The codecov project level check is failing because I removed a bunch of lines of code. But the patch check (which is the required one) is passing and the full codecov report shows that all the new lines are covered and that number of uncovered lines actually decreased.

Thanks for updating this. I've looked through and from a dashboard approach I think we will be good with all this. I'll leave the rubber stamping for @dannyjacobs

Looked through changes one more time. All seem consistent and ok.
