[bundler/bundler] Bump net-http-persistent to 3.0.1

* Adds an extra artifice task to vendorize new `connection_pool`
dependency.

* Cherry-pick's needed Windows fix not yet merged into master branch of
`net-http-persistent`.

* Update bundler usages to be compatible with the new version, and fix
unit specs.
