Summary

@ninabarbakadze recently did some phenomenal work on feat: add TxStatus rpc endpoint. This preliminary work indexed committed transactions so users could see that they were committed in a lightweight manner and not need to rely on BroadcastTxCommit or the Tx endpoint + the kv_indexer.

As part of providing greater tracing ability for users transactions is to modify the TxStatus endpoint such that it gives the current status of the transaction. They can be as follows:

• Unknown(default case)
• Pending (in the mempool)
• Committed (in the secondary index in the block store)
• Rejected (as decided by the mempools rejected cache
• Evicted (has been kicked out of the mempool because of a TTL or not a high enough fee)
