flowprobe: add api messages to obtain current state
Type: improvement With this change: - add dump/details messages to obtain interfaces for which IPFIX flow record generation is enabled; - add get message to obtain parameters; - add a new message to set parameters with validation present and to correspond with get/set naming; - add tests for get/set parameters and dump/details interfaces. Change-Id: I09f6ec990171ac8bcb9d2f5c92629803b8ab6c28 Signed-off-by: Alexander Chernavin <achernavin@netgate.com>
