CookieClient appends cookies with the same name

[ohadgur]

Hi team, I moved the question from discord.
I started using the CookieClient decorator to honor set-cookie headers in the server's response.

I noticed that if the server keeps returning the same cookie name, domain, and path, but a different value, the cookies on the next request are concatenated. This seems like a bug looking at https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.2

This causes the server (non-armeria) to fail the requests since they are getting too big.

I created a small reproducer here - https://gist.github.com/ohadgur/4c10c14b50fc742cffff883237362e07

Thanks!
