proxy: v2.174.0 (#8042)

This release fixes an issue that could prevent proxies from sending HTTP
Upgrade requests (e.g., for websockets) through multi-cluster gateways.

Many dependencies have been updated, notably including a new version of
`h2` that improves debug logging, avoids panics in time-related
operations, and fixes an issue with parsing certain types of headers.

This change also updates the `regex` crate to address RUSTSEC-2022-0013,
which could theoretically allow maliciously crafted ServiceProfile
resources to consume an arbitrary amount of proxy resources.
