Add input_process option to Moore

Kara Mattiolirequested to merge
add_input_process_flag_for_Moore into master

This MR adds an input_process option so that the input process ('Hlt1' or 'Hlt2') can be specified to Moore when running with gaudirun.py or LbExec. The input_process is 'Hlt1' by default.

This option is used to configure the necessary bankKillers when re-running HLT2 on data that has already been processed by HLT2 (i.e. passthrough, nobias streams). An example of this is shown in Moore!2159 (merged), with details of the bankKiller issue described in Moore#524.
