CI job: scylla-staging/valerii/vp-longevity-aws-custom-d2-workload1-multidc-big#15
Originally the CI job failed to collect logs.
I triggered appropriate command manually.
Started adding links myself one by one.
After pressing "submit" button for the fifth log link all the log link records got duplicated:

So, at first, it must be smart enough to filter out duplicates.
Must be protected from double-clicks, any multiple clicks on the "submit" button.
And, secondly, we should be able to remove, at least, manually added log links any time.
