(QENG-1128) Beaker no long auto recursively scps directories...

to systems under test

- issue was :recursive variable was being carried over successive calls
  to scp_to.  To prevent this, just set it based upon the file type
  being called
(MAINT) repair spec (copy_module_to and docker)

- failure from update to copy_module_to ignore list
- was allowing sleeps which slows down spec test execution
