CreateClientTLSCredentials creates client-side TLS transport credentials using certificate and key files from testdata/x509 directory.

DefaultClientListener returns a basic xds Listener resource to be used on the client side.

DefaultClientResources returns a set of resources (LDS, RDS, CDS, EDS) for a client to generically connect to one server.

SetupManagementServer performs the following: - spin up an xDS management server on a local port - set up certificates for consumption by the file_watcher plugin - creates a bootstrap file in a temporary location - creates an xDS resolver using the above bootstrap contents Returns the following: - management server - nodeID to be used by the client when connecting to the management server - bootstrap contents to be used by the client - xDS resolver builder to be used by the client - a cleanup function to be invoked at the end of the test.

StartManagementServer initializes a management server which implements the AggregatedDiscoveryService endpoint.
