* Deprecate nodebin in favor of go binary

Resolve more inconsistencies with version selection (heroku#666)

* Resolve more inconsistencies with version selection

Data from the dark-launch of the new resolve logic shows the same result
99.5% of the time. There are two classes where things differ:

- Version numbers of leading v's. Ex: v10.15.3
- Cases where the resolve function fails and the nodebin request succeeds

To that end I've updated the underlying semver library to correctly parse the
leading v's and bumped the version.

I've also written a retry loop around resolve to match the `--retry 5`
option in the curl request

* Add linear backoff to retry logic
