OpenWrt 21.02 branch

[Hannu Nyman]

I built my first OpenWrt 21.02 test build and noticed that opkg is unable to 
download any package lists. When I try to update package list with 21.02, 
opkg gives error about signature file download errors.

Signature file download failed.
Remove wrong Signature file.

Looking at the 21.02 download directories, the package dirs are indeed 
missing the normal .sig signature files.

There should likely be a 21.02 release key, which should be added both to the 
keyring and to the 21.02 buildbot config (?). So far the newest key in the 
keyring is the 19.07 release key.

The 21.02 buildbots are already running and end-users are eagerly waiting to 
test 21.02, so there are already forum discussions about 21.02 opkg.
E.g. https://forum.openwrt.org/t/21-02-snapshot-error-opkg-update/89054


jow has added the release keys for 17,01, 18.06 and 19.07, but I am unsure 
who should do it now, so I am spamming this to some possible suspects.
