docs(clientlibs): add crystal client lib

client library docs

Can you outline what crystal is? I can't figure it out via the github org and some related websites have cert errors. Based on this I'd probably like to delay this doc addition.

hiya @jan--f

could you let me know which sites you looked at that have cert errors?

crystal is a compiled programming language with C bindings and ruby-like syntax: https://crystal-lang.org/

Sure, https://cloudnative.cr/ is the offending location, linked from https://github.com/cloudnative-cr.

Thanks! Is there a plan to locate the client libs under the https://github.com/crystal-lang org?

The here proposed clients libs looks like a new effort by individuals. We try to not "endorse" projects before the respective community has made up their mind (and keep our doc churn low). So is it perhaps a bit early to add this here?
