[FR] ThreatGrid analyzer SSL verification option

Feature description
Update ThreatGrid analyzer with an option that makes possible to turn on or off the verification of ThreatGrid appliance's SSL certificate.

Describe the solution you'd like
Currently our ThreatGrid appliance's API has a web server certificate signed by our company CA. The analyzer is complaining, because according to it it's not a valid certificate:

Traceback (most recent call last):
File "/usr/local/lib/python3.8/site-packages/urllib3/connectionpool.py", line 670, in urlopen
httplib_response = self._make_request(

self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)

It would be great if ThreatGrid analyzer had an option that enables or disables checking ThreatGrid's HTTP certificate.

No file, test, or entry point is named in the issue. Locate the ThreatGrid analyzer and its HTTP request configuration, then determine how an option can control certificate verification; done means the analyzer supports enabling or disabling that check for the appliance API.
