Allow to specify tls options for Redis

[arnaud-thorel-of]

Hi everyone,

During my tests with sourcebot, I figured that it doesn't work with external redis using tls with SNI validation because of the construction of ioredis connector :

sourcebot/packages/backend/src/index.ts

Line 42 in 5c4b0ce

const redis = new Redis(env.REDIS_URL, {

Is it possible de add in new versions the ability to override tls options ?

In my case I just need the servername options, but maybe other has to configure other options

tls: { servername: *SERVER_NAME* }

List of tls options : https://nodejs.org/api/tls.html

Maybe you can allow us to override the entire tls, or map each tls option with a VAR_ENV

REDIS_TLS={ servername: myServerName}
REDIS_TLS_SERVERNAME=myServerName

Thx a lot for your responses
