Yardstick: User interface for Yardstick.

Currently Yardstick doesnt have any UI which gives detail analysis
of the test-results.
This commit generates a HTML page after the execution of a command
"yardstick report generate <task-ID> <TC-name>" which intern
can be executed after the execution of test-case.
Used: Highcharts.js for the graphs.

JIRA: YARDSTICK-280

Change-Id: Ic98cc348719f3922bff178f52e7944a4a931763a

+Yardstick User Interface
+========================
+
+This interface provides a user to view the test result
+in table format and also values pinned on to a graph.
+
+
+Command
+-------
+::
+
+    yardstick report generate <task-ID> <testcase-filename>
+
+
+Description
+-----------
+
+1. When the command is triggered using the task-id and the testcase
+name provided the respective values are retrieved from the
+database (influxdb in this particular case).
+
+2. The values are then formatted and then provided to the html
+template framed with complete html body using Django Framework.
+
+3. Then the whole template is written into a html file.
+
+The graph is framed with Timestamp on x-axis and output values
+(differ from testcase to testcase) on y-axis with the help of
+"Highcharts".
