Allow Maximum Session Duration attribute to be cloned via "Clone existing role".

[Yagyansh]

Is your feature request related to a problem? Please describe.
I've increased my session duration of AWS Console via ConsoleMe to 4 hours. To achieve the same, I had to change the maximum duration session for all the roles that I need to assume to 4 hours.
Now, when I create a new role via ConsoleMe I don't get an option to increase the maximum session duration for that role in ConsoleMe. Also, if I create a blank role for cloning with 4 hours max duration, the new cloned role doesn't copy this attribute and has the default 1 hour of maximum session duration.

Describe the solution you'd like
Either while creating a new role the user should get an option to increase the maximum session duration for the role OR role cloning should copy all the attributes of the source role including the maximum session duration, to the new cloned role.
