MGMT-24243: Add option for a delay when applying static network config on minimal ISO

 A delay can be used on hosts that need time to discover their NICs.
 The delay can be set per infra-env, to specify how many second to wait before mapping host MACs to interfaces. If it's not set then the delay will be the value of an environment variable with the default value being 0. MCE users can set that environment variable to configure a default delay.
