PR description
PIE 2284 : https://pegasys1.atlassian.net/browse/PIE-2284
We should expose an equivalent to Parity's trace_transaction API (https://wiki.parity.io/JSONRPC-trace-module.html#trace_transaction). Most of this work should have already been done as part of the previous tracing APIs implemented. This task involves exposing an additional API that will take a transaction hash and provide its trace, and making sure the output is compatible with Parity's.
