Epoch can be ticked by IR in the background. Because the only usecase
for this is to apply some changes, the right behaviour is ignoring an
error, not retrying.

Testing:

$ cat multi.sh
#!/bin/sh

ADM="../node/bin/frostfs-adm"

for i in $(seq 1 10); do
    "$ADM" morph force-new-epoch \
        -c frostfs-adm.yml \
        -r http://morph-chain.frostfs.devenv:30333 &
done

sleep 10

$ ./multi.sh
