Symptom reporting (individual reporting / UI work)

[cankisagun]

In the individual reporting section, we propose to ask self-reporting users whether they have any symptoms. Given 40% of Covid19 carriers have only mild symptoms and may not have tested, it's important to identify interactions with these individuals as well

This issue builds on Issue #18

User flow in the UI should be:

• User indicated whether they have symptoms or not.
• If user has indicated to have symptoms, use chooses the following options:
• [ ] Fever >100.0 F or >38 C, time_since
• [ ] Cough, time_since
• [ ] Shortness of breath, time_since

Note: The symptom questionnaire can be extended. As a next step, we need to run a symptom assessment algorithm locally on the client side and only communicate the outcome to the SafeTrace API (Intel SGX)

I would use "cough" rather than "dry cough".
