Description

Right now, we express time in different ways in different modules/sections of the config, e.g.:

        "main": {
                "layer-duration-sec": 300,
                "sync-request-timeout": 60000
        },
        "p2p": {
                "conn-keepalive": "48h",
                "dial-timeout": "1m",
                "response-timeout": "60s",
               

Right now there's no way of seeing a wallet's phrase or private key via the CLI. The private key is visible via the wallet file, but not the phrase--it uses an Entropy rather than saving the words.

It would be good to have a command, e.g.:

> feeless wallet secret --id

The output would vary depending on the wallet type:

> feeless wallet secret --id xxx # phrase, must match
