Make Subject Alternative Names in the self-signed certificate Configurable.

[AnsonHwang86]

Here is decoder of default Edgedb self-signed Certificate.

Subject Alternative Names: 127.0.0.1

After I added this cert to system store on Mac, there is a ERR_CERT_COMMON_NAME_INVALID ERROR show in Chrome browser, Because I don't use IP 127.0.0.1

I have to run following command to regenerate the Cert and prevail key and overwrite the default one, and the Error will disappear.

C:/"Program Files"/git/usr/bin/openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes -keyout edbprivkey.pem -out edbtlscert.pem -subj "/C=US/ST=NY/L=NewYorks/O=COMA/OU=Section/CN=Edgedb Server" -addext "subjectAltName=IP:192.168.192.72"

In many case we don't use 127.0.0.1, my advice is to make this IP configurable in docker Environment Variable, it will save our time.
