We can make the implementation more robust by adjusting our assumptions
and leverage explicit file modes for syncing. Additionally we going to
assume that we want to clean up and can't really recover if thos
operations (file close and removal) fail.
* utilise file mode for majority of concerns
* improve test coverage by covering more assumptions
* signature parity with ioutil.WriteFile
* always clean up
Replaces #160

The previous code was very trusting assuming that
rational actors will use this code. However, Byzantine
actors don't care and in the case of the linked issue
negative lengths can be sent to this code unfettered
having been received from a peer.
This code is essentially just a sign change from
`==`
to
`<=`
and we've gutted out that attack by being more defensive.
* Init `\health` rpc endpoint
* remove additional info from `\health` rpc endpoint
* Cleanup imports
* Added time threshold for health check
* Update rpc doc
* Remove unnecessary checks for blocktime creation lag
* Clean up of unnecessary config usage
if enough peers are marked good eventually some will become unmarked, so
good to have a force that will continue to cycle them back into good
territory!

Those functions are unused in the whole Tendermint Github
organization plus they were unnecessariy verbose and could
have been concisely replaced with
```go
func RightPadString(s string, totalLength uint) string {
return fmt.Sprintf("% *s", totalLength, s)
}
func LeftPadString(s string, totalLength uint) string {
return fmt.Sprintf("% -*s", totalLength, s)
}
```
delete them anyways
