• Describe this change in 1-2 sentences:
  A command that allows to load files as a part of the command pipeline

Problem

It would be useful to load a file after some commands have already been executed as a part of the pipeline. The load command extends positional arguments' functionality.

• JIRA ticket (optional): None

Solution

Added the needed command

Action

Should be squashed on merge

Could this be used to load URLs and MBIDs as well? If so you might be better off passing the argument list to load_to_Picard() for processing rather than adding the arguments directly using add_paths().

Could be, I wasn't sure if it should be added. What's your take on this @zas @phw ?

My thinking was that it should operate the same as files, etc. entered on the command line, as described by @zas in his comment on #2137.

So you're saying that we should ditch the positional argument FILE_OR_URL in favor of adding a LOAD command which would be the only way to load something to picard?

Nope, in addition. Basically picard would be equivalent to picard -e LOAD . The idea is to let user use only -e commands to achieve the same thing.
