Hi,
We are using moodle 3.4.x on a 4 node cluster . I had the same problem as you describe. After many scripting and headaches i tried "MooSH"
MoodleShell https://moosh-online.com/
This is our time saver now when we updating our plugins .
Just install it on your Server (or start with a test machine)
Example for install or update a plugin .
directly from your command prompt
"moosh plugin-list (lists all Moodle plugins) "
if you i.ex want to install a plugin called "mod_choicegroup" just
moosh plugin-install -d mod_choicegroup 2018070900
installs the updated plugin without to go via your webside.
After this you just need to purge your cache and you are fine .
So , just give it a try
