Add timeout to channel builder

[dmitrii-ubskii]

Usage and product changes

We introduce a timeout in the gRPC channel so that the driver correctly fails when the server is available but unresponsive.

Resolves #672.

Implementation

Trivial Change

• This change is trivial and does not require a code or architecture review.

Code

• Packages, classes, and methods have a single domain of responsibility.
• Packages, classes, and methods are grouped into cohesive and consistent domain model.
• The code is canonical and the minimum required to achieve the goal.
• Modules, libraries, and APIs are easy to use, robust (foolproof and not errorprone), and tested.
• Logic and naming has clear narrative that communicates the accurate intent and responsibility of each module (e.g. method, class, etc.).
• The code is algorithmically efficient and scalable for the whole application.

Architecture

• Any required refactoring is completed, and the architecture does not introduce technical debt incidentally.
• Any required build and release automations are updated and/or implemented.
• Any new components follows a consistent style with respect to the pre-existing codebase.
• The architecture intuitively reflects the application domain, and is easy to understand.
• The architecture has a well-defined hierarchy of encapsulated components.
• The architecture is extensible and scalable.

Chosen arbitrarily. Anything less than a second or so is too strict for slow connections, but going significantly over a minute would probably be too long.

Let's verify that this timeout doesn't drop query requests with complicated, long-running queries. For example, write a simple read query, put a sleep on the server side for 2 minutes, and let it run. This should not fail. But if you put your server sleep on connection, it should fail after 1 minute.

If this works, everything should be fine.
