Cosmetic fixes

Rever memory overhead of `kata` to 350 megs.

Commit text example :

The pod overhead of peer pods is expected to be lower than
regular kata pods. Use a different set of values for the
`kata` and `kata-remote` runtime classe, like upstream kata
does.

Current numbers for `kata` are kept. New numbers for `kata-remote`
are taken from upstream.The numbers can probably be refined some
more through experiments.
