Fix registration of tasks.

Daniel Roseman · Daniel Roseman · commit 75f3d36815d0 · 2017-04-26T14:58:52.000+01:00
Importing show_commands was causing several tasks to be registered
under the 'elasticsearch' command, because of the ordering of imports.
Fix this by importing it directly within the help function where it is
used.
