ignore empty lines in rabbitmqctl output (#43722)

Browse source 
* ignore empty lines in rabbitmqctl output

this fixes a bug with rabbitmq 3.7.5
rabbitmqctl can return empty lines, breaking the rabbitmq_parameter module
especially in a new vhost, the command rabbitmqctl list_parameters -q -p <vhost> will return an empty line

* Strip empty line in rabbitmqctl output
