Returns a json object containing mining-related information.
Result:
{                              (json object)
  "blocks" : n,                (numeric) The current block
  "currentblockweight" : n,    (numeric, optional) The block weight of the last assembled block (only present if a block was ever assembled)
  "currentblocktx" : n,        (numeric, optional) The number of block transactions of the last assembled block (only present if a block was ever assembled)
  "difficulty" : n,            (numeric) The current difficulty
  "networkhashps" : n,         (numeric) The network hashes per second
  "pooledtx" : n,              (numeric) The size of the mempool
  "chain" : "str",             (string) current network name (main, test, regtest)
  "warnings" : "str"           (string) any network and blockchain warnings
}
