config.toml rework, Default Values, chain details lookup

[danbryan]

I would like to be able to simplify some of these kube jobs. For example, take job-osmosis-index-epoch-day

    [log]
    level = "info"
    pretty = true

    [base]
    api = "http://x.x.x.x:1317"

    # index transactions
    index-chain = false
    # start-block = 11220706
    start-block = 11245200
    end-block = -1

    # Block Events
    index-block-events = false
    block-events-start-block = 8732500
    block-events-end-block = -1

    # Osmosis Epoch Indexing
    index-epoch-events = true
    epoch-indexing-identifier="day"
    epoch-events-start-epoch=803
    epoch-events-end-epoch=806

    rpc-workers = 4
    throttling = 1.25005
    block-timer = 1000
    wait-for-chain = false
    reindex = false
    prevent-reattempts = false
    wait-for-chain-delay = 5
    exit-when-caught-up = false
    dry = false

    [lens]
    rpc = "http://x.x.x.x:26657"
    account-prefix = "osmo"
    chain-id = "osmosis-1"
    chain-name = "osmosis"

    [database]
    host = "x.x.x.x"
    port = "5432"
    database = "db"
    user = "user"
    password = "password"
    log-level = "error"

to this

    [base]
    api = "http://x.x.x.x:1317"

    # Osmosis Epoch Indexing
    index-epoch-events = true
    epoch-indexing-identifier="day"
    epoch-events-start-epoch=803
    epoch-events-end-epoch=806

    [lens]
    rpc = "http://x.x.x.x:26657"
    account-prefix = "osmo"
    chain-id = "osmosis-1"
    chain-name = "osmosis"

    [database]
    host = "x.x.x.x"
    port = "5432"
    database = "db"
    user = "user"
    password = "password"

The goal is to make config.toml easier to read and know what its doing. I think we should also be able to infer the account prefix, chain-id, chainname from the RPC /API server. No need to have it in the config.toml.
