config: apply two default miner option

[zzzckck]

Description

1.Apply default value for Recommit and MaxWaitProposalInSecs

[Eth.Miner]
GasCeil = 70000000
GasPrice = 100000000
VoteEnable = true

with this configuration, Eth.Miner.Recommit & Eth.Miner.MaxWaitProposalInSecs will be 0, while their default value should be 3000000000 and 30 respectively.
This PR it to fix the default value issue of these 2 options.

2.Change the default value of the two options.
It would be more reasonable to change default value these 2 options:

• Recommit: from 3000000000(3 seconds) to 10000000000(10 seconds)
  Notice: Recommit is a experimental value, it could be removed, but leave it for now as it has not big side effect.
• MaxWaitProposalInSecs: from 30s to 45s
  Node restart could take ~40second
  Here if one of the restart log from a BSC full node, it took ~37 seconds

It could be partial fix for #2986
