* Add a new operating mode to rippled called reporting mode
* Add ETL mechanism for a reporting node to extract data from a p2p node
* Add new gRPC methods to faciliate ETL
* Use Postgres in place of SQLite in reporting mode
* Add Cassandra as a nodestore option
* Update logic of RPC handlers when running in reporting mode
* Add ability to forward RPCs to a p2p node
At this point all of the jss::* names are defined in the same
file. That file has been named JsonFields.h. That file name
has little to do with either JsonStaticStrings (which is what
jss is short for) or with jss. The file is renamed to jss.h
so the file name better reflects what the file contains.
All includes of that file are fixed. A few include order
issues are tidied up along the way.
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"
* RPC `ledger` command returns all queue entries in "queue_data"
when requesting open ledger, and including boolean "queue: true".
* Includes queue state. e.g.: fee_level, retries, last_result, tx.
* Respects "expand" and "binary" parameters for the txs.
* Remove some unused code.
This is designed for use by proxies in front of rippled. Configured IPs
can forward identifying user data in HTTP headers, including
user name and origin IP. If the user name exists, then resource limits
are lifted for that session. However, administrative commands are still
reserved only for administrative sessions.
