[v12] Added release server publishing retry

[camscale]

• Added release server publishing retry
• dronegen: Run auto_publish 10 times (from 3) in a loop

Change the drone generation to use a loop to run the auto_publish
relcli command instead of listing them one-by-one and loop 10 times
instead of 3. The loop will terminate the first time relcli succeeds.

The loop has an || false at the end to ensure the loop command fails
if all invocations of relcli fail. With set -e, even though the exit
status of the loop is non-zero, the shell seems to continue. With the
|| false at the end, it makes it exit on failure. I'm not sure exactly
how drone runs the commands so this may not be necessary but it seems
safer.

e.g.

set -e
for i in $(seq 10); do false && break; done
echo hello

This will echo "hello" even though all invocations inside the loop
failed.

set -e
for i in $(seq 10); do false && break; done || false
echo hello

This will not echo "hello" - set -e causes an exit before that command
due to the || false.
