# Internal: method to send duration for a transaction
# it checks if it can send metrics with the current transaction name
# or a default transaction name and sets the transaction name accordingly
#
# === Arguments:

# * +kvs+ A hash containing key/value pairs, only the value of :TransactionName will be relevant
#
# === Returns:
# The result of the block.
#
# === Assigns:
# The transaction_name to kvs[:TransactionName]
