bugfix: Cleanup of traffic gen api and default traffic values
Both documentation and traffic generator API are updated to match current code logic. Additional default values are added into TRAFFIC_DEFAULTS dictionary. Constructor of TestCase class uses default values from TRAFFIC_DEFAULTS instead of magic numbers.

functions:
- * param **trials**: Number of trials to execute
+ * param **traffic**: A dictionary with detailed definition of traffic
+ pattern. It contains following parameters to be implemented by
+ traffic generator.
+
+ Note: Traffic dictionary has also virtual switch related parameters,
+ which are not listed below.
+
+ Note: There are parameters specific to testing of tunnelling protocols,
+ which are discussed in detail at `integration tests userguide`_
+
+ * param **traffic_type**: One of the supported traffic types,
+ e.g. **rfc2544**, **continuous** or **back2back**.
+ * param **frame_rate**: Defines desired percentage of frame
+ rate used during continuous stream tests. It can be set by test
+ parameter iLoad or by CLI parameter iload.
+ * param **bidir**: Specifies if generated traffic will be full-duplex
+ (true) or half-duplex (false).
+ * param **multistream**: Defines number of flows simulated by traffic
+ generator. Value 0 disables MultiStream feature.
+ * param **stream_type**: Stream Type defines ISO OSI network layer
+ used for simulation of multiple streams.
+ Supported values:
+
+ * **L2** - iteration of destination MAC address
+ * **L3** - iteration of destination IP address
+ * **L4** - iteration of destination port of selected transport protocol
+
+ * param **l2**: A dictionary with data link layer details, e.g. **srcmac**,
+ **dstmac** and **framesize**.
+ * param **l3**: A dictionary with network layer details, e.g. **srcip**,
+ **dstip** and **proto**.
+ * param **l3**: A dictionary with transport layer details, e.g. **srcport**,
+ **dstport**.
+ * param **vlan**: A dictionary with vlan specific parameters,
+ e.g. **priority**, **cfi**, **id** and vlan on/off switch **enabled**.
+
+ * param **trials**: Number of trials to execute.
* param **duration**: Duration of continuous test or per iteration duration
