Taurus does not work with custom .properties file passed to Apache JMeter through command line

Taurus does not work with custom .properties file passed to JMeter through command line. There is only one way to make it work - place the custom properties in user.properties.

I have tried renaming the custom properties file as user.properties and it worked.

Taurus should be able to work with custom .properties file (Apache JMeter) passed as a command line argument.
