Create localcopy deploy-hook

Deploy-hook to very simply copy files to set directories and then execute whatever reloadcmd
the admin needs afterwards. This can be useful for configurations where the "multideploy"
hook (in development) is used or when an admin wants ACME.SH to renew certs but needs to
manually configure deployment via an external script (e.g. The deploy-freenas script for TrueNAS Core/Scale
