v0.8.0 - the context update

What's Changed

Monitoring:

• introduce callbacks for every retryable operation and for session and connections by @jxsl13 in #48
• add multiple StatXXX pool methods for fetching the current pool state

Dependencies:

• Bump codecov/codecov-action from 3 to 4 by @dependabot in #47

Bugfix:

• fix incorrect context passed by @jxsl13 in #49
• implement correct connection flow control handling for publishers (fixes #50)

Breaking Changes:

• the context update by @jxsl13 in #51
  • Size() methods are now called Capacity() and Size() refers to the currently idle connection/sessions in a pool
  • Publish timeout and AwaitConfirms timeout were removed in favor of a single context for both (pool.Publisher)
  • all methods now require a context to be passed. (fixes #44)
  • HandlerFuncs, BatchHandlerFuncs, TopologyFuncs receive an additional context parameter which is canceled upon pool context cancelation

Feature:

• add a special error for rejecting messages pool.ErrReject (pool.ErrRejectSingle) (fixes #46)
• removes internal queue and replaces it with a Go channel (removes dependency) (fixes #4)

CI/CD:

• all tests can now be run in parallel
• limit parallelization of tests in GitHub Action to 2 tests being run in parallel due to weird GitHub runner behavior.
