[GoodID] location certificate

[sirpy]

Add an api endpoint to issue location certificate inputs:

• location data from browser
• user ip
• optional mobile number returns certificate

Create a method to issue location certificate

• verify that location data from gps matches user ip geolocation
• if mobile number is given, verify that user mobile was verified and matches our stored hash
• if gps+ip resolves to same country or mobile is verified, then use the country from gps or mobile country code
• issue certificate using veramo.io sdk

External services required

• to get client IP + country data (we may use one to get ipv6 for captcha, need to check does it provides country info)
• to get country from location coordinates (google reverse geo coding or find other one as google have strict limits for the free usage)
• with mobile phones everything looks fine - just check country code from the number (we may have this list at the phone input)

1. we're already using an external API to get country from IP address - won't change
2. for reverse geo coding I suggest to use https://nominatim.openstreetmap.org/reverse?format=jsonv2&lat=-34.44076&lon=-58.70521 It's free and open, does not requires You to create any account

@johnsmith-gooddollar In the case where gps+ip AND verified mobile differ, which one takes precedence?

@patpedrosa data from the phone. actually if user have verified mobile, we don't even check gps and IP

@L03TJ3 why is this on hold?

[L03TJ3]

@decentralauren That was requested by @vldkhh when we have items moving up from technical-review but are not really 'qa-able' yet
