[Esclide]

Please use let's encrypt for ssl certificate.
Add force redirect from http to https.
Check and validate with sslabs service.

1. Need to update react so it would initiate https api url.
2. Need to fis API, right now it's not working:
   curl -i https://188.124.37.185:5000/api/wiki
   curl: (35) error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number

I've fixed. However there are still more points:

1. Need to add 301 redirect from http to https.
2. Need to ensure that local development environments (usually without ssl) are working fine.
   For the second point probably environment variable should be set and interpreted. Or something like this: https://stackoverflow.com/questions/4723213/detect-http-or-https-then-force-https-in-javascript
