CSIT-1178: Prepare for bursty MRR
+ All suites and tests still refer to MRR instead of BMRR (or FRMOBL). + API change: Traffic should pass with maximum rate first argument got a default value, thus it needs to be moved towards the end of argument list. + Consequently, the value for it has been deleted from suites. + Test message is now compatible only with BMRR parsing. - Reporting of transmit rate is left as TODO. + Global test __init__ with new way of giving defaults to global variables. + The new keyword is put into robot_enhancements.robot resource. + Number of trials and trial duration are now configurable. - Bootstrap scripts have no support for overriding the defaults yet.

+| Ensure Global Variable
+| | [Documentation] | Give default value (from environment or code) to variable.
+| | ...
+| | ... | Ideally we would just use Variables table to set global variables.
+| | ... | Unfortunately, __init__ files are special (among other things)
+| | ... | by the fact that variables set in the table are not available
+| | ... | for (sub)directory suites.
+| | ... | Therefore we are using BuiltIn.Set_Global_Variable explicitly.
+| | ... | While we are running code here, we allow environment variables
+| | ... | to override the default values.
+| | ... | If environment variable name is not specified (or empty),
+| | ... | the upper case of the variable name is used, prefixed by "CSIT_".
+| | ... | The --variable parameter to pybot takes precedence to environment.
