APIv2: 'resize' resizes always to 80 characters

[marusak]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description
Using containers/resize or exec/resize to resize TTY session ignores w parameter and resizes always to 80 characters.

Steps to reproduce the issue:

sudo podman run -dt fedora bash
7d481626f41cec219a377c7fb20be9e25d37f9965e9e7e868b9361952ddef597

2. sudo podman attach 7d481626f41cec219a377c7fb20be9e25d37f9965e9e7e868b9361952ddef597 and just type more than 80 characters. You should be able to type as many, as you want.

3. run in different terminal sudo curl -X POST --unix-socket /run/podman/podman.sock "http://d/v1.24/libpod/containers/7d481626f41cec219a377c7fb20be9e25d37f9965e9e7e868b9361952ddef597/resize?w=200&h=20" and then in the one where you are still attached you can type only 80 characters and then the line will start to overwrite itself. Feels like the w is ignored and 80 is used as default value?

It does not seem like this should be a big issue? Is this fairly easy to fix?
