Visit https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/bootstrap/v3/bootstrap.proto#envoy-v3-api-msg-config-bootstrap-v3-bootstrap to learn more about the syntax. If set, this is the Bootstrap configuration used for the managed Envoy Proxy fleet instead of the default Bootstrap configuration set by Envoy Gateway. Some fields within the Bootstrap that are required to communicate with the xDS Server (Envoy Gateway) and receive xDS resources from it are not configurable and will result in the `EnvoyProxy` resource being rejected. Backward compatibility across minor versions is not guaranteed. We strongly recommend using `egctl x translate` to generate a `EnvoyProxy` resource with the `Bootstrap` field set to the default Bootstrap configuration used. You can edit this configuration, and rerun `egctl x translate` to ensure there are no validation errors.
`concurrency`	integer	false	Concurrency defines the number of worker threads to run. If unset, it defaults to the number of cpuset threads on the platform.
`extraArgs`	string array	false	ExtraArgs defines additional command line options that are provided to Envoy.

Setting this field to true would merge all Gateway Listeners under the parent Gateway Class. This means that the port, protocol and hostname tuple must be unique for every listener.

`shutdown`	ShutdownConfig	false	Shutdown defines configuration for graceful envoy shutdown process.
`backendTLS`	BackendTLSConfig	false	BackendTLS is the TLS configuration for the Envoy proxy to use when connecting to backends. These settings are applied on backends for which TLS policies are specified.

Only the following headers will be included in the check request to an HTTP authorization server: Host, Method, Path, Content-Length, and Authorization. And these headers will always be included to the check request to an HTTP authorization server by default, no matter whether they are specified in HeadersToExtAuth or not.
`failOpen`	boolean	false	FailOpen is a switch used to control the behavior when a response from the External Authorization service cannot be obtained. If FailOpen is set to true, the system allows the traffic to pass through. Otherwise, if it is set to false or not set (defaulting to false), the system blocks the traffic and returns a HTTP 5xx error, reflecting a fail-closed approach. This setting determines whether to prioritize accessibility over strict security in case of authorization service failure.
