Update docs for web3.eth API

[NikitosnikN]

What was wrong?

Docs for eth.getTransactionReceipt, eth.waitForTransactionReceipt is outdated. Response of these methods is different:
It includes logsBloom, status fields and does not include root field.

Also it is impossible to find information about transaction status (if it is successful or it was reverted) in web3.py docs, but this info can be found in simular section web3.js docs.

How can it be fixed?

Update web3.eth API method responses, add info about returned parameters
