swarmctl -z Component Log Level

swarmctl -z [component] -V [level]
can run with multiple components in the same call: swarmctl -z component1 component2 [-V [level]]
this option allows you to change the log level of a particular component instead of changing the log level of every component
useful when troubleshooting very specific issues, especially in large environments where debug level produces too much data to sift through
run with no options to see the default levels
use like "-z -V 0" to reset all components to their default log level
use with -a to affect all nodes
