Release - 1.2.9

[ryanio]

Description

This PR introduces web3.js version 1.2.9 beginning with 1.2.9-rc.0.

Release notes

In addition to dependency updates, small bug fixes for the ABI Coder change in 1.2.8, and many documentation improvements, this release extends the transaction event API for more granular tracking of transaction submissions.

These additions were proposed by client engineer @benjamincburns in #3438 and should:

• make it easier to ensure that transactions are submitted in order (see web3+HttpProvider reusing nonce when doing parallel contract deploy using Promise.all #1846)
• make transaction timing in performance benchmarking tools more precise
• make it easier to monitor the transaction submission process for debugging purposes

The new / changed Promievents are:

Event	Description	Handler args
sending	Fired immediately before transmitting the transaction request, after all intermediate requests such as eth_chainId, eth_estimateGas, or eth_gasPrice have completed.	transactionPayload
sent	Fired immediately after the request body has been written to the client, but before the transaction hash is received	transactionPayload
confirmation	Behaves as it does today, but includes the block hash for the most recently mined block in the event handler arguments	confNumber, receipt, latestBlockHash

Also of note...

As reported in #3432 by @dmihal, Web3 has long had some interaction issues with provider middle-ware like web3-provider-engine that uses http and provides an event emitter interface. The library has assumed that these packages support subscription endpoints when they don't. This bug should be fixed by PR #3517.
