Fast sync when running Besu on cloud providers

A known RocksDB issue causes fast sync to fail when running Besu on certain cloud providers. The following error is displayed repeatedly:

...
EthScheduler-Services-1 (importBlock) | ERROR | PipelineChainDownloader | Chain download failed. Restarting after short delay.
java.util.concurrent.CompletionException: org.hyperledger.besu.plugin.services.exception.StorageException: org.rocksdb.RocksDBException: block checksum mismatch:
....

This behaviour has been seen on AWS and Digital Ocean.

Workaround -> On AWS, a full restart of the AWS VM is required to restart the fast sync.

Fast sync is not currently supported on Digital Ocean. We are investigating options to add support for fast sync on Digital Ocean.
