faucet: update

This PR tries to improve https://github.com/bnb-chain/bsc/pull/2680
If the node did not set `Eth.Miner` in config.toml, the default GasCeil
will be 30000000, it is not an accurate number for both BSC mainnet and testnet.
Set it to 0 means disable the transaction GasLimit check, i.e. the TxPool will
accept transactions with any GasLimit size.

+# 1.Background
+This is to support some projects with customized tokens that they want to integrate into the BSC faucet tool.
+
+## 1.1. How to Integrate Your Token
+- Step 1: Submmit a Pull Request to [bsc develop branch](https://github.com/bnb-chain/bsc/tree/develop) with relevant token information: `symbol`, `amount`, `icon`, `addr`. Append these information in [Section 2: Token List](#2token-list)
+- Step 2: Wait for approval, we will review the request, and once it is approved, the faucet tool will start to support the customized token and list it on https://www.bnbchain.org/en/testnet-faucet.
+- Step 3: Deposit your test token to designated address(0xaa25aa7a19f9c426e07dee59b12f944f4d9f1dd3) on the BSC testnet.
