[10-10EZ/10-10EZR] Temporarily disable BGS call for the COLA update weekend

[coope93]

Summary

• This work is behind a feature toggle (flipper): YES
• Added a flipper toggle to our /rating_info endpoint that allows the endpoint to return a 0 be default instead of calling the underlying BGS service. This will be turned on during a planned BGS outage to prevent calls to the service. Veterans will receive a 0 from this endpoint, but the forms allow them to add their own information later.
• 10-10 Health Apps
• Flipper toggle hca_disable_bgs_service

Toggles are enabled by default in specs, so disabling it here to keep the specs consistent.

Sorry for the random comment, just saw this and I was curious, will this show Veterans that their disability is zero percent?

@bosawt Yes, at least when calling this specific endpoint from our forms. We use this to populate it on the front end, but there are also other places on the form for the Veteran to self report their disability rating. We only intend to use this this weekend so we don't call the BGS service when we know it will be down. Right now, if BGS service returns an error/fails we treat it as returning a 0 disability rating on the front end. So functionally this is the same behavior as if we just let the service return the error response.

Ah ok, makes sense
