add proxy configuration support

[mattlqx]

Description

This pull adds explicit proxy configuration for push-jobs-client. While undocumented, setting the same attributes in the config file as chef-client for proxies (e.g. http_proxy, https_proxy, etc.) does work for pushy-client. This configuration can be configured via the node['push_jobs']['proxy']['http'] and node['push_jobs']['proxy']['https'] hashes. node['push_jobs']['no_proxy'] string attribute can also be specified for which domains/suffixes are to be proxy bypassed.
