Lua Resty Qless Versions Save

• Fix: Issue where global table can no longer be modified (since Redis 6.2.7). Thanks to @hrsantiago for the fix.

• Fixed issue when passing in an existing (but broken) redis connection

• Feature: Support passing in existing redis connections, or callbacks to create / destroy
• Fix: Qless workers now call set_keepalive each time they exit
• Test: Code coverage reporting and some improved coverage

• Updated qless-core (now supports Redis >= 3.2)
• Job's now always return a value

• Jobs are no longer required to return true in order to be completed by the worker.
• Added opm dist.ini file.

• Bugfix: Workers were not accepting redis connection parameters, meaning timeouts were defaulted to 100ms. Thanks @keen99 for the report.
• Added a luarocks spec as requested by @saucisson.

Minor release:

• Pulled the latest qless-core sub repo.
• Workers are now named using the pid and their worker id, instead of a random hex. Requires lua-nginx-module 0.9.20 (OpenResty 1.9.x).

• Bugfix: Jobs can be failed with no message (rather than script fatal)
• Feature: Jobs can be queued with a custom jid, via the options table

• Moved Redis connection to use lua-resty-redis-connector.
• Workers now retry on interval when the Redis connection is failing.
• Implemented queue-level config_get/set.

• Include pre-made versions of the qless-core libraries in lib.
