Add support role specific configuration values

[kpheasey]

Add support role specific configuration values for the following options:

• :sidekiq_env
• :sidekiq_log
• :sidekiq_require
• :sidekiq_tag
• :sidekiq_queue
• :sidekiq_config
• :sidekiq_concurrency
• :sidekiq_option_per_process
• :sidekiq_options

@seuros Just wanted to add that this is a more complete solution for role specific configuration as compared to the following pending pull requests. Additionally, It uses the [role]_[option] naming scheme that is already being implemented with :sidekiq_processes

• run sidekiq on different roles #149
• Support per-process options & better per-role options #141
• [WIP]Allow different queue per role on capistrano3 #117
• Support different queues per role #85

Same question

[lustercr]

hi @seuros, is there an alternative way to support this in the current version, I been using a fork from @kpheasey for over a year and things worked fine, however, I'm now upgrading to latest Capistrano and I'm facing the issue you fixed here #160.

if you think this is a feature that will contribute to the project, I'm more than glad to help reforking and applying @kpheasey changes to latests version.

in my case I use different configs not only for a different number of process per machine size, but i distribute the queues to different machines, critical and fast processing queues go to one machine role and the non-critical or heavy process such export go to a different set of machines.
