**Added** support for concurrent SidecarScope conversion. You can use `PILOT_CONVERT_SIDECAR_SCOPE_CONCURRENCY` to adjust the number of concurrencies.
    Its default value is 1 and will not be executed concurrently. 
    When `initSidecarScopes` consumes a lot of time and you want to reduce time consumption by increasing CPU consumption,

	ps.initProxyConfigs(env)
	ps.initWasmPlugins(env)
	ps.initEnvoyFilters(env, nil, nil)
	ps.initGateways(env)
	ps.initAmbient(env)

	// Must be initialized in the end
	ps.initSidecarScopes(env)
	return nil
}
