Rethink the whole thing

[freak12techno]

How it works for now: checks every N seconds if there's a diff from the last state, reporting the diff. If some validator is going to jail, it'll report a lot of messages.

How it may work:

1. store a state in a json file or so, reload it from disk on restart
2. have a struct for each valcons (ValidatorState) that has the following: valcons, valoper, moniker, missed blocks, jailed
3. have a set of groups (MissedBlocksGroup) in config, represented by a struct with the following fields: start value, end value, emoji when a validator's missed blocks counter enters/leaves this group, message for it
4. have a struct (ReportMessage) that has the following fields: emoji, valoper, moniker, missed blocks, message
5. have a function that maps previous and current ValidatorState using MissedBlocksGroup array and jailed param to an optional Message if a validator state was changed, either if validator is jailed/unjailed, or if a validator's missed blocks counter changes causing it to fall under a different MissedBlocksGroup (if validator either skips more blocks or signs and the window moves.
