Robotframework request package upgrade changes

Current working package version
   robotframework-requests            0.7.2

To Test:
      pip3 install robotframework-requests -U
                 or
      # Once this commit is merged.
      pip3 install -r requirements.txt

      Version latest:
      robotframework-requests         0.9.3

Refer Documentation:
   https://marketsquare.github.io/robotframework-requests/doc/RequestsLibrary.html

What is not changed:
     - The test cases under directory tests/ is not modified and is
       deprecated but you can continue using it with older package
       and configuration using

       git clone -b v3.0-stable https://github.com/openbmc/openbmc-test-automation

Tested:
      Upstream HW_CI test list, firmware code update and few other
      test suite like ipmi, certificate, dumps, ffdc and redfish
      test suites.

Note: I have not tested end to end, so it is likely there could be
      grey areas where it could fail but should be minor w.r.t
      response data format.

Resolves:  openbmc/openbmc-test-automation#2105
