creates a new options instance from a given hash, which optionally define the following:

:transport |
type of transport to use (set to “unix” for |
:addresses |
bucket of peer addresses (can be a list of IP addresses, a hash of domain to list of adddresses; paths should be used for |
:io |
open socket, or domain/ip-to-socket hash, which requests should be sent to |
:persistent |
whether to persist connections in between requests (defaults to |
:resolver_class |
which resolver to use (defaults to |
:resolver_options |
hash of options passed to the resolver |
:ip_families |
which socket families are supported (system-dependent) |
:origin |
HTTP origin to set on requests with relative path (ex: “api.serv.com”) |
:base_path |
path to prefix given relative paths with (ex: “/v2”) |
:max_concurrent_requests |
max number of requests which can be set concurrently |
:max_requests |
