Use blocking reader to fix race in test

The `TestCanceledContext` test in `twofactorverify_test.go` tests
the scenario wherein the request context gets canceled in the
middle of the request.

A race can occur though when the input gets read before the context
is canceled which can result to a different error: instead of
having the context canceled, the OTP will be blank.

To fix it, we use a blocking reader as input to simulate "waiting
for input" scenario. This way, reading the input will never be
finished and the context cancelation can be done appropriately.

Use the images provided by Gitlab to run tests

MustStrictWhiteListPolicy panics when configured incorrectly. So here we
use the error returning version instead.

Changelog: added

Instead of interpreting the configuration for every new connection, we
can rely on a closure to simplify the proxy handler path. This is more
similar to how the provided MustStrictWhiteListPolicy works which will
be added in a later commit.

Fix broken Gitaly integration tests

Gitaly started to require `Repository` information for certain
commands like upload-pack, upload-archive, and receive-pack.

However, gitlab-shell tests are sending `git_object_directory` and
`git_alternate_object_directories` that do not exist.

To fix the tests, we set those to an existing directory in the
created repository.

It also excludes 1.12.1 version to break the cycling dependency
that loads a lot of obsolete libraries

The changes are the result of running

go mod tidy -compat=1.17

We don't support 1.16 for a while, this command just cleans up the
unnecessary dependencies
