As we migrate to luci, all tryjobs will be done by the same "builder", namely 'findit_variable' on 'luci.chromium.try'
Thus, it is unnecessary to specify a trybot and mastername for each.
Instead, having `'use_swarmbucket': True` as one of the entries for the builder should be enough for findit to use such default values.
