Subject: [PATCH] allow disabling mining pool fetching in offline environments

Previously, Mempool strictly required fetching mining pool data from
Github and failed when this was not possible, e.g. in offline
environments.

This patch allows disabling pool fetching.
When disabled, empty pool data is inserted into the DB, which
effectively turns off block pool classification.
