Zebrad enviroment variables

All zebrad subcommands support the following enviroment variables:

ZEBRAD_CACHE_DIR: The directory to store zebra data just as state, blocks, wallet, etc.
ZEBRAD_LOG: Manipulate the log level. Regex is supported.

Examples:

Use a custom data directory:

export ZEBRAD_CACHE_DIR="/my/zebra_data_dir"
zebrad start

Output all info messages:

export ZEBRAD_LOG="info"
zebrad start

Output block_verify with trace level and above every 1000 blocks:

export ZEBRAD_LOG="[block_verify{height=Some\(BlockHeight\(.*000\)\)}]=trace"
zebrad start

Note: Log options are processed in this order: verbose flag, command stdout, enviroment variable, config file.
