[Bug]: Growing /opt/netdata/usr/share/netdata/web/v3 #21327

Bug description

The folder /opt/netdata/usr/share/netdata/web/v3 seems to grow forever:

$ find /opt/netdata/usr/share/netdata/web/v3 | wc -l
16931
$ du -sm /opt/netdata/usr/share/netdata/web/v3
2018	/opt/netdata/usr/share/netdata/web/v3

It seems like this keeps growing forever with more and more javascript files, now reaching 2GB in size
It seems to generate new files whenever an update of the binary is performed by the looks of it.

Expected behavior

If new assets are generated, old ones should maybe be cleaned out

Steps to reproduce

  1. Install netdata using kickstart-static
  2. Profit after several weeks

Installation method

kickstart.sh
