Add giset command to set generic dictionary settings

[sm-shaw]

Add giset command to modify generic dictionary settings and print generic to print the current settings out.
Modifications are persisted to the SQLite storage.
Update has also been made to tclpy fork to keep commands in sync sm-shaw/libtclpy@f53b1fc
Examples of usage of both commands as shown.

hammerdb>giset commandline keepalive_margin 600
Changed commandline:keepalive_margin from 10 to 600 for generic

hammerdb>print generic
