TMC Low supports tied-array beam (PST) observations and Improved Obs State aggregation

Summary

Added

TMC SubarrayNode v0.23.1 supports:

• delay_poly and jones keys per beams for low CBF
• TMC nodes updated to support PST observations, verified using OSO-TMC AssignResources and Configure schema which includes PST and PSS
  • AssignResources OSO-TMC schema for PSS and PST : https://gitlab.com/ska-telescope/ska-tmc/ska-tmc-low-integration/-/blob/main/tests/data/centralnode/assign_resources_json.json?ref_type=heads 
  • Configure OSO-TMC schema for PSS and PST: https://gitlab.com/ska-telescope/ska-tmc/ska-tmc-low-integration/-/blob/main/tests/data/subarray/configure_low.json?ref_type=heads 
• PST observation to be based on having pst and pss keys optionals under TMC-CSP schema. (This is to support PST and non PST observations) (This is in accordance with SKA Tel Model)

This TMC low v0.18.0 does'nt support:

• TMC provides delay tracking for PST beam at bore-sight.
  (This is planned for PI24 due to scope change and insufficient  information in PI23)
   

Changed

• Obs State aggregation logic is improved in Subarray Node.
• rule-engine python package is used to define rules for Aggregated obs state of subarray node.
  • Following is the link to the file where rules defined for each obs State
    • https://gitlab.com/ska-telescope/ska-tmc/ska-tmc-subarraynode/-/blob/master/src/ska_tmc_subarraynode/manager/transition_rules/obs_state_rules.py?ref_type=heads
• Created new class for storing event data.
  • This class store event of obs state, pointing state, dish mode, long running command result received from leaf nodes.
• Created new separate aggregation process which perform obs state aggregation based on event data and aggregation rules.
