Clean up interface and installation of the CCF python scripts

[cmickeyb]

The CCF python scripts are operationally reasonable. However, parameterization and expectations for default values are somewhat inconsistent. And... the scripts are useful well beyond the CCF ledger nodes to which they are currently restricted. The work items suggested are:

1. canonicalize the command line parameters to all of the scripts
2. convert them to a python installable format
3. build a python package that can be installed (and managed)

All this should be under the assumption that they will be installed in $PDO_INSTALL_ROOT/bin where all of the other PDO python scripts are installed.

Several of these issues were addressed in #470. closing.
