Allow setting of the local listener address

[kernle32dll]

Issue #, if available:
#14 (slightly related)

Description of changes:

1. What:
   This change introduces the ability to change the listener address, under which the port forwarding will listen. The default of localhost is kept.

2. Why:
   I am using a PortForwardingSession, which runs inside a GitLab CI Service. This allows me to abstract the forwarding logic away, and have it re-usable. However, since the forwarding session is not running "locally" anymore, it needs to be accessible from outside the service. With a listener address of localhost, this is not possible. I am successfully using 0.0.0.0 akin to whats written in Accessing forwarded port from Docker container #14, and this works flawlessly.

@bbankeAWS Thank you! Since this feature has already been implemented, as you can see in the 'Files changed' section above, I believe we don't need to discuss it extensively, and we can simply proceed with the code review.

Friendly bump, this would benefit us a lot!

Sure would be nice to be able to run AWS SSM via docker - this is a blocker for that.

Please merge this PR, its a pain to use session manager in a Docker image right now.

This feature is a must! It would be really great to see it working

@Yangtao-Hua @ziwangj Merry Christmas! How’s it going? Do you have any updates?

This would be really useful for binding multiple connections to the same port on different loopback addresses. I would love to specify a localAddress parameter.

Our use case looks like forwarding to multiple HTTPS hosts at once, and using local DNS overrides to make them accessible via their original hostnames.

e.g.

127.0.1.1:443 website-a
127.0.1.2:443 webiste-b
127.0.1.3:443 api-c

Because of the harcoded localhost, our workaround is to run the SSM port forwarding inside docker, bridge the connection to another port inside docker via socat bound to 0.0.0.0, then use docker port mapping to expose these on the host machine.

With the small change of supporting arbitrary bind addresses, we could remove docker & socat from our flow and have a far simpler experience.
