Turn off stateful filtering for egress proxies to allow cluster traffic to be forwarded to tailnet. Allow configuring stateful filter via tailscaled config file. Deprecate EXPERIMENTAL_TS_CONFIGFILE_PATH env var and introduce a new TS_EXPERIMENTAL_VERSIONED_CONFIG env var that can be used to provide containerboot a directory that should contain one or more tailscaled config files named cap-<tailscaled-cap-version>.hujson. Containerboot will pick the one with the newest capability version that is not newer than its current capability version. Proxies with this change will not work with older Tailscale Kubernetes operator versions - users must ensure that the deployed operator is at the same version or newer (up to 4 version skew) than the proxies.
