Scenario parser should honor double and single quotes in values

[sahankj2000]

Description

Scenario parser does not honor double quotes and single quotes inside scenario definitions.

Issue: #1888

Previous and new behaviours in parsing

previous:   param="test1" -> param="test1"
new:        param="test1" -> param=test1

previous:   param="test 1" -> 5811 ERROR [main] ERRORHANDLER Unable to recognize scenario cmd spec in '1"'
new:        param="test 1" -> param=test 1

previous:   param=\"test1\" -> param=\"test1\"
new:        param=\"test1\" -> param="test1"

previous:   param="\"test 1\"" -> 5751 ERROR [main] ERRORHANDLER Unable to recognize scenario cmd spec in '1\""'
new:        param="\"test 1\"" -> param="test 1"

• New behaviours are made similar to the behaviour when running directly from commandline
