`ParamsSpecs`, `{Workflow,Profile,Flow}Params`: Refine error handling

[azriel91]

Enables better user experience for automation software upgrades.

Currently:

• ParamsSpecs returns Error::ParamsMismatchError for all mismatches, and CmdCtx fails to be built, so *Cmds would not be able to be run. For unused stored specs, it would be better to warn / automatically upgrade.

• {Workflow,Profile,Flow}Params discards unknown parameters, instead of notifying the user. We should notify the user to help them recognize:

  • Potential typos
  • Param additions / removals / modifications

Everywhere that uses the following snippet, needs to be reviewed for what should be surfaced to the user:

storage
    .serialized_typemap_read_opt(/* .. */)
    .await
    .map(|type_map_opt| {
        type_map_opt
            .map(TypeMapOpt::into_type_map)
            .map(_::from)
    })

All of those places are to do with some kind of "upgrade":

• Addition of a data type -- States, ParamsSpec, Params, {Workflow,Profile,Flow}Params.
• Modification of a data type: Adding / removing / changing fields
• Removal of a data type
