> When loading multiple modules into master/agent, one has to merge all module metadata
(library name, module name, parameters, etc.) into a single json file which is then passed
on to the --modules flag. This quickly becomes cumbersome especially if the modules are coming
from different vendors/developers.
> An alternate would be to allow multiple invocations of --modules flag that can then be
passed on to the module manager. That way, each flag corresponds to just one module library
and modules from that library.
> Another approach is to create a new flag (e.g., --modules-dir) that contains a path to
a directory that would contain multiple json files. One can think of it as an analogous to
systemd units. The operator that drops a new file into this directory and the file would automatically
be picked up by the master/agent module manager. Further, the naming scheme can also be inherited
to prefix the filename with an "NN_" to signify oad order.
