DAWN-214 ⁃ p2p transaction generator plugin

[blockone-syncclient]

Phil:

In order to test the p2p infrastructure under the greatest load, I would like a plugin that generates transactions in a configurable way. My idea is that this plugin will behave more-or-less like the http plugin except that it will synthesize transaction data rather than accept it from an external source.

I also expect a multinode testnet to support multiple nodes with this plugin. I assume that the plugin will read a config file, probably json. The launcher app can be enhanced to compose appropriate sets of config files. Configuration items include such details as a range of accounts to produce, contract[s] to load, execution frequency, etc. Finally the plugin should periodically report metrics as appropriate.

As I complete the remaining details of the p2p, I think this will give a more flexible and robust means of driving load tests.

ATC: run the following sequence of steps. note the curl commands end with the http argument.

programs/launcher/launcher -p1 n2 l none
echo "plugin = eosio::txn_test_gen_plugin" >> staging/tn_data_01/config.ini
programs/launcher/launcher ~~p1 n2 -~~nogen

curl --data-binary '["inita", "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"]' http://localhost:8889/v1/txn_test_gen/create_test_accounts

curl --data-binary '["inita", "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"]' http://localhost:8889/v1/txn_test_gen/fund_accounts

curl --data-binary '["one", 400]' http://localhost:8889/v1/txn_test_gen/start_generation

tail tn_data_00/stderr.txt

observe transactions in the output. e.g:

Re-opening (we probably closed this prematurely). Placing in Sprint 6.
