feat: added connectionEndpoint parameter to subscriptionOptions

[n1te1337]

This PR adds connectionEndpoint parameter to subscriptionOptions.

if specified, the connection endpoint will be registered with the connectionEndpoint value as opposed to extracted from the event payload (as ${domainName}/${stage}). Useful when using API Gateway Custom Domains.

Closes #112

@n1te1337 thank you very much! 👍

@michalkvasnicak no worries, happy to help. Out of curiosity, how often do you cut new releases?

[michalkvasnicak]

@n1te1337 basically every time there is something to release I release it. One thing I'd like to mention is that if you use this library in production and you're happy with it, please consider mentioning your project/company in #106 🙂

Also version 1.0.0-alpha.16 is released.

That's the plan, it's still WIP but I'll add it there when it's live

PS. Just tried the new version and works as expected with API Gateway Custom Domains 🙂
