Add 'type' param to ledger_data and ledger rpc commands (RIPD-1446):

Browse Source 
The 'type' field allows the rpc client to specify what type of ledger
entries to retrieve. The available types are:

    "account"
    "amendments"
    "directory"
    "fee"
    "hashes"
    "offer"
    "signer_list"
    "state"
    "ticket"
