# Generic function to query the agent/ICS via the REST or DMAAP interface.
# Used by all other agent/ICS api test functions
# If operation sufffix is '_BATCH' the the send and get response is split in two sequences,
# one for sending the requests and one for receiving the response
# but only when using the DMAAP interface
# REST or DMAAP is controlled of the base url of $XX_ADAPTER
# arg: (PA|ICS|CR|RC GET|PUT|POST|DELETE|GET_BATCH|PUT_BATCH|POST_BATCH|DELETE_BATCH <url>|<correlation-id> [<file> [mime-type]]) | (PA|ICS RESPONSE <correlation-id>)
# Default mime type for file is application/json unless specified in parameter mime-type
# (Not for test scripts)
