Change CLI live-config-reload options into flags 

The previous format of --live-config-reload=VAL had a specific set of
allowed values which may not immediately be obvious. Instead, there are
now two flags which control the behavior:

    --live-config-reload
    --no-live-config-reload

If a user tries to specify both, the option parsing will fail with this
message:

    error: The argument '--no-live-config-reload' cannot be used with
        '--live-config-reload'
