Fix: Use network host parameter when launching local rpc network node

[danceratopz]

What I did

I modified brownie so that the host parameter configured with the networks CLI is now used when launching a local RPC network node. This is required to enable use with dockerized RPC clients (host in this case must be set to 0.0.0.0).

Related issue: #1533

How I did it

I made some small changes to brownie/networks/rpc/*.py.

How to verify it

The modifications to the fixtures and units tests in this PR test that the network node launches and correctly configures the host parameter.

They do not test that the parameter is correctly passed from networks CLI though, this can be verified locally very easily by modifying the host parameter via the CLI and starting hardhat/ganache:

Ganache:

brownie networks modify development host="http://127.0.0.2"
brownie console --network development
# ->
# Launching 'ganache-cli --accounts 10 --hardfork istanbul --gasLimit 12000000 --mnemonic brownie --port 8545 --host 127.0.0.2'...

Hardhat:

brownie networks modify hardhat host="http://127.0.0.2"
brownie console --network hardhat
# ->
# Launching 'npx hardhat node --port 8545 --hostname 127.0.0.2'

I didn't manged to get the py39 tests to pass on Windows (https://github.com/danceratopz/brownie/actions/workflows/core-ganache-3.9.yaml). Problems with web3.py causing flakiness on Windows?

This PR would also solve #1312.
