      Design for asynchronous communication between TMC devices is worked out.

      End to end implementation of one command in TMC is available as a POC.

      The implementation passes the relevant integration tests.

      A sample implementation of TelescopeOn command on the Central node-mid is worked out to invoke commands in an asynchronous manner on the lower-level device.
      Here is the link to the TelescopeOn command implemented on CentralNode:
      https://gitlab.com/ska-telescope/ska-tmc-centralnode-mid/-/blob/master/src/ska_tmc_centralnode_mid/telescope_on_command.py
      And the exact usage of command_inout_async API:

    Description

      This spike is part of the next steps identified during resolution of bugs (SP-1488 in PI#9) to address issues such as timeouts for long running commands. The spike focuses on designing the TMC commands and their callback methods.  It models the invocation of commands in an asynchronous way within TMC without breaking the functionality or creating new bugs/issues. This is verified by implementing one command as a POC.

      Consider how to use and incorporate the design solutions produced by SP-1640 and SP-1827.

      The actual work on TMC refactoring to fully implement asynchronous commands will be performed later, when the results of SP-1827 are well tested (and may even require SP-1627 and SP-1628 to be completed).
