…plugins#134)

* refactor: extract :uri_or_empty validator to extension module

* make connection, request, and socket timeouts configurable

default values were chosen from the current default behaviour of these
transport options as provided by the Manticore transport adapter we provide to
the Elasticsearch Client:

> ~~~
> request_timeout (integer) — default: 60 — Sets the timeout for requests.
> connect_timeout (integer) — default: 10 — Sets the timeout for connections.
> socket_timeout (integer)  — default: 10 — Sets `SO_TIMEOUT` for open connections. A value of 0 is an infinite timeout.
> ~~~
>
> -- [Manticore::Client#initialize](https://www.rubydoc.info/gems/manticore/Manticore/Client#initialize-instance_method)

I have elected _not_ to allow an infinite `socket_timeout` by requiring
the provided value to be positive, as I can see no valid use-case of such
using Elasticsearch's HTTP API.

* timeouts: increase default socket timeout to 60s

Mirrors behaviour of prior `Net::HTTP` adapter used in version 4.3 of this
plugin, which had a read timeout of 60s.

* bump version to 4.8.0
