    TS-4458: disabling configuration modification breaks reloading

    If you set ``proxy.config.disable_configuration_modification`` to 1, 
records configuration callbacks are never registered, so if you update 
records.config and then reload with ``traffic_ctl config reload``, the new 
configuration is not actually applied.

    TS-4458: Return RecErrT from Rec APIs.

commit 733e0be79507dc8631026378d8975b50dac607fd

    TS-4458: Fix disabled modification behaviour.
    
    If you set proxy.config.disable_configuration_modification to 1 to
    prevent writing to records.config, various other features broke.
    For example, configuration change callbacks were never run, so
    reloading configuration did nothing.
    
    This change retains the callbacks and just disables the persistence
    of changes to records.config. Note that if you change a record with
    the API, you still have to touch records.config to reload the old
    values.
