SAL topics for indexed components have a field named {Name}ID (e.g. MTHexapodID or ScriptID). I propose to rename this to salIndex (was private_index; changed after 2022-05-03 CAP meeting) to simplify usage and make topics more uniform. It is a nuisance to have to compute the name of the field.

I think this only affects Python code (and ts_sal internally). I don't know of any indexed non-Python CSCs. The Java Camera CSCs, ATMCS, etc are not indexed.

Also note that most code that deals with a specific index of a SAL component never sees this field. ts_salobj or ts_sal does the right thing when you specify an index.

Code that will need updating includes:

• Chronograf dashboards that filter on a specified SAL index.
• Some LOVE code, such as the ScriptQueue display.
• ts_scriptqueue, which uses this field to command a specific script.
• Possibly some Jupyter notebooks.

I have converted both ts_salobj and ts_scriptqueue and it was trivial. I expect the Chronograf dashboards to also be easy and am offering to do the work.
