Fix Download Timeout

When downloading large plugins, it can timeout (e.g. ruby-runtime). The
archive::download supports a timeout value which defaults to 120
seconds, but this plugin class doesn’t have any support to override
this value. This allows for the ability to adjust the timeout value for
large plugins.

Error message when download timeout exceeds 120 seconds:

Error:

nload[ruby-runtime.hpi]/Exec[download archive ruby-runtime.hpi and
check sum]/returns: change from notrun to 0 failed: Command exceeded
