weave status showing targets, though no hosts were provided during weave launch #3779
Description
What you expected to happen?
During weave launch, no hosts are specified as targeted hosts to connect. So i would expect, "weave status targets" output should show empty.
Example of how weave process running on Master host,,

What happened?
weave gets launched successfully, and initially it shows targets empty. some of the peers also gets discovered as for few peer hosts we are mentioning the initially launched weave IP as master to connect during weave launch.
But over a period of time, i see "weave status targets" getting filled up with all its peers discovered/connected. I expect, the targets should stay empty, as no hosts are given during weave launch.
Would like to understand on how "weave status targets" getting filled on Master Host ?
Not able to find any info on weave troubleshooting/faq. So posting here. Thanks for your help in advance !
How to reproduce it?
On Host1:
launch weave without any hosts to connect
on Host2/Host3/Host4:
launch weave with Host1 to connect
Expected Host 1 should have "weave status targets" empty always.
Expected Host1 in "weave status targets" in Host2/Host3/Host4: which is looking as expected.
