Add lat lng to firestore on service provider documents so we don't have to always make an api call

[paul-rinaldi]

Is your feature request related to a problem? Please describe. Too many API calls

Describe the solution you'd like Only call the geocode API when lat lng doesn't exist on the document. Asynchronously store the lat lng on the document when the geocode API is called.

Describe alternatives you've considered None

Additional context Service Page, Index in Server/
