Improvement to the DBZ SMT step

Improvement

• Remove the field asking for the transformation name and do it automatically for the user reducing the input needed from the user.

Reason for the ask: As the user may not care about that what the transformation name/key being used in the implementation code as long as he gets the desired output, it also put extra responsibility on the user to come up with a unique name. 

Solution: Since this whole configuration is presented to the user for verification on the last step(Review step) it would not be ideal to just use the random value for the transformation name as it can create difficulty for the user to relate. Thus we can try to autogenerate the transformation name by appending some unique value to the selected SMT type which would increase the probability for the user to relate the configuration on the last Review page.
