Recoverable Tango Devices in TMC

Demonstration that a tmc subarray tango device (e.g. sdp/csp sub array leaf and subarray node) in 'State' == FALSE can be re-initialised when the command 'Reset" is given which will cause it to enter the 'state' 'OFF as per currently agreed observation state machine https://developer.skatelescope.org/projects/lmc-base-classes/en/latest/State_Machine.html Given the ongoing work with SS-82 , demonstration using umbrella charts rather than full SKAMPI is sufficient for acceptance. Future stories/work beyond the scope of this feature to incorporate this work into SKAMPI at a future date will be required

1. Simulated scenarios for SubarrayNode for ObsState to be FAULT, and CspSubarrayLeafNode, SdpSubarrayLeafNode for its State to be FAULT. 2. Observed that SubarrayNode's state does not change to FAULT. 3. Implemented Reset command on SubarrayNode, SdpSubarrayLeafNode and CspSubarrayLeafNode. As a part of the Reset command, few Attributes values are updated in the Init command for eg. receptorId list, scan duration, scan configuration, etc are now getting reset. Also added a mechanism to kill the alive threads wherever applicable. MR link for ska-tmc-subarraynode: https://gitlab.com/ska-telescope/ska-tmc-subarraynode-mid/-/merge_requests/25 4. Created a new taranta dashboard with Reset buttons to demonstrate feature SP-1953 . 5. Implemented integration test case for Reset command with the scenario of bringing subarrayNode into the FAULT Observation state and sdpsubarrayleafnode, cspsubarrayleafnode into FAULT state.

Ska-tmc : https://artefact.skatelescope.org/#browse/browse:docker-internal:v2%2Fska-telescope%2Fska-tmc%2Ftags%2F0.8.7 Ska-tmc-subarraynode-mid : https://artefact.skatelescope.org/#browse/browse:docker-internal:v2%2Fska-telescope%2Fska-tmc-subarraynode-mid%2Ftags%2F0.3.8 7. Published ska-tmc-mid chart version 0.4.10 containing Reset functionality on CAR. Link: https://artefact.skatelescope.org/#browse/browse:helm-internal:ska-tmc-mid%2F0.4.10%2Fska-tmc-mid-0.4.10.tgz 8.
