We try to perform API-version negotiation as lazy as possible (and only execute
when we are about to make an API request). However, some code requires API-version
dependent handling (to set options, or remove options based on the version of the
API we're using).
Currently this code depended on the caller code to perform API negotiation (or
to configure the API version) first, which may not happen, and because of that
we may be missing options (or set options that are not supported on older API
versions).
This patch:
- splits the code that triggered API-version negotiation to a separate
Client.checkVersion() function.
- updates NewVersionError to accept a context
- updates NewVersionError to perform API-version negotiation (if enabled)
- updates various Client functions to manually trigger API-version negotiation

1. As daemon.ContainerStop() documentation says,
> If a negative number of seconds is given, ContainerStop
> will wait for a graceful termination.
but since commit cfdf84d5d0 (PR #32237) this is no longer the case.
This happens because `context.WithTimeout(ctx, timeout)` is implemented
as `WithDeadline(ctx, time.Now().Add(timeout))`, resulting in a deadline
which is in the past.
To fix, don't use WithDeadline() if the timeout is negative.
2. Add a test case to validate the correct behavior and
as a means to prevent a similar regression in the future.
3. Fix/improve daemon.ContainerStop() and client.ContainerStop()
description for clarity and completeness.
4. Fix/improve DefaultStopTimeout description.
Fixes: cfdf84d5d0 ("Update Container Wait")

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.
