Description

Skip search if the search string is empty.

Issues Resolved

For environments that specify node['rsyslog']['server_ip'] instead of using search, you be able set node['rsyslog']['server_search'] to nil to not perform the search instead of having to specify a dummy search such as 'role:DOES_NOT_EXIST'
