tests: Improvement of step driven testcases

A set of improvements was introduced to enhance step driven
testcases capabilities.

Details:
* delay among test steps is configurable by TEST_STEP_DELAY
  parameter
* step driven tool function exec was renamed to exec_shell
* new step driven tool function exec_python was introduced to execute
  a python code
* new step driven object sleep was introduced to pause test execution
  for defined number of seconds.
* fixed bug in settings.validate_getValue() to correctly validate
  access of parameters modified by TEST_PARAMS
* new #PARAM() macro was introduced to allow references among
  configuration parameters
* multistream support has been added into ixnetrfc2544v2.tcl,
  which is used for tunneling protocols test (op2p deployment)
* fixed bug in op2p deployment to list interfaces and flows
  from both bridges involved in the test
* test report updated to state exact rfcxxxx type of traffic
  type, e.g. rfc2544_continuous
* test report of step driven testcases was updated to contain
  measured values from traffic generator in CSV report
* method for ovs flow comparison was modified to normalize
  IPv4 CIDR network addr (e.g. 10.0.0.5/8 => 10.0.0.0/8)
