Add TimeOut to Abort call in dispose

[lukebakken]

Supersedes #1075

Fixes #938

cc @CeesKass

Note: this also modifies integration tests to add the test suite name to the connection name. This makes it much easier to know which tests may be having issues by looking at the RabbitMQ logs.

Proposed Changes

While testing my usage of the RabbitMQ.Client library against a blocked RabbitMQ server I encountered an infinitely hanging dispose of my publisher see #938

Types of Changes

What types of changes does your code introduce to this project?
Put an x in the boxes that apply

• Bug fix (non-breaking change which fixes issue Connection.Abort uses a timeout of infinity by default, potentially blocking Connection.Dispose #938)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause an observable behavior change in existing systems)
• Documentation improvements (corrections, new content, etc)
• Cosmetic change (whitespace, formatting, etc)

I'm not sure if this is a breaking change or not, I did not dive deep enough into the Abort procedure to know if anything can break when calling with a timeout
