Comma in strong password incompatible with connection string format

We have an auto-provisioned Redis instance in a cloud environment. The password we're provided is generated for us, is very long, and has a lot of special characters... including, sometimes, commas.

We then have systems that try to attach to Redis using a connection string. Unfortunately, the way SE.Redis parses connection strings based on comma delimiters, it means if our generated password has a comma in it, then part of the password gets interpreted as another host. Exception messages have stuff like this buried in them: SocketFailure on *9?9pi?aK__6fAKSH:6379/Subscription (where *9?9pi?aK__6fAKSH is the half of the password after the comma).

Looking through the parsing code it doesn't appear there's a way to escape commas. That might be a good addition to help in edge cases like this.

Start by locating the connection-string parsing entry point and the existing password handling, then reproduce the issue with a Redis password containing a comma. Done means comma-containing passwords are parsed without treating the remaining password text as another host, with the behavior covered by tests.
