This commit switches the linter for Go code from golint to staticcheck.
Golint has been deprecated since last year and staticcheck is a
recommended replacement.

- bump golang 1.17 -> 1.18
- bump alpine 3.14 -> 3.15
- revendor
We need to use golang instead of golang:alpine because it does not
contain git anymore. This should be fine as we are not enabling CGO,
thus not linking against musl instead of libc.

This commit adds a new test suite to the e2e tests that validates
multi-cluster connectivity in Kilo. This is really just an extension of
the testing of the Peers CRD and related tooling that also exercises the
`--allowed-ips` flag of the `kgctl` tool.

This commit enables the filtering of e2e tests that should be run when
using the Makefile's `e2e` target through the specification of the
`BASH_UNIT_FLAGS` environment variable. The value of this variable will
be passed as arguments to the `bash_unit` command, enabling filtering of
tests.

Currently, each test suite spins up its own kind cluster, which results
in longer e2e test times as each test suite needs to wait for the
cluster to be ready and for images to download. This commit creates two
new virtual test suites that are run before and after the actual e2e
tests and are responsible for creating and destroying a kind cluster
respectively. Any test suite that needs a fresh cluster can still spin
up its own using the `create_cluster` helper in the lib.sh file.

We seem to be running into
https://github.com/kubernetes-sigs/kind/issues/2240: kube-proxy is
crashlooping, which in turn causes CoreDNS to fail to connect to the API
server over the Service CIDR, which in turn cases DNS resolution to fail
in the cluster, which in turn causes the e2e tests to fail.
To address this,
this commit bumps the kind version to 0.11.1.

This commit splits the e2e tests into different suites that all reuse
helper functions from the lib.sh file. This split ensures that the tests
within a suite can all have the same setup, e.g. all tests depending on
a full-mesh will be set up with a full-mesh, and is resilient against
changes in test ordering.

This commit adds testing of the VPN feature of Kilo to the e2e tests.
Also, in order to make the tests less flaky, this commit ensures that
the Kilo Pods use the "root" kubeconfig to connect to the API rather
than the Kubernetes API's cluster IP, which can become unavailable when
networking is reconfigured.

This commit refactors the e2e tests in the following ways:
* bump the version of `bash_unit` to 1.7.2: the previous version was
from 2018;
* remove the unused `block` function;
* fix the order of `block_unitil_ready_by_name` and `check_ping`: we
should not attempt to interact with pods before they are considered
ready;
* extract the retry logic into a reusable function called `retry`; and
* retry the `check_adjacent` function for robustness.

Tests are using kind, adjacency and bash_unit.
A kind cluster is spun up and the previously build container image of
Kilo is loaded into it.
Adjacency and a curl container is started.
From the curl container a http request is send to the adjacency service.
The test fails if curl returns an unexpected result.
Two test are run. One with `mesh-granularity=full` and `location`.
The e2e test is only run for pull request because it is a bit flaky for
automatic nightly runs.
