This commit allows the kind cluster configuration to be parameterized at
call time. This enables the test suite to build multiple clusters with
different configurations, e.g. different CIDRs, different numbers of
nodes, etc.

This commit modifies the logic of the check_adjacent helper so that
rather than expecting the argument to be n^2+n it expects simply n. This
makes it easier to update the caller when the number of nodes in the
cluster changes.

This commit modifies the e2e shell scripts so that the KUBECONFIG
variable does not need to be exported. This will become important once
we allow the e2e test suite to launch multiple clusters, e.g. to test
multi-cluster connectivity.

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 a new e2e test fot the recently introduced
allowed-location-ips annotation. This test annotates the control-plane
node with an allowed IP and then ensures this IPs is reachable from
the curl helper Pod, which is now guaranteed to be scheduled on a
worker node.

This commit adds an e2e test that ensures that invalid Kilo Peers are
rejected thanks to the improved OpenAPI v3 validation.

The recent test refactor wrapped the adjacency check in a `retry`,
however, the `check_adjacent` function had an `assert` in it, which
meant that the test would fail immediately and not be retried. This
commit moves the assertion out of the check, which also allows for
improved code reuse.

Users can specify IPs with the annotation "allowed-location-ips".
It makes no difference which node of a location is annotated.
The IP should be routable from the particular location, e.g. a printer in
the same LAN.
This way these IPs become routable from other location.

This commit adds better handling of the default kubeconfig location in
the kgctl binary for cases where the `$KUBECONFIG` environment variable
is not set. In these cases, kgctl will default to
`$HOME/.kube/config`, putting it in line with tools like `kubectl` and
`kind`.

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.

- upgrade from apiextension v1beta1 to v1
- generate yaml manifest for crd intead of applying it at runtime
- users will have to apply the manifest with kubectl
- kg and kgctl log an error if the crd is not present
- now validation should actually work

This commit fixes lint warnings produced by shellcheck. This simplifies
some of the `if`s and protects against variables with spaces. We may
want to consider shellchecking all scripts in the repo.

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.

This commit cleans up some typos in the documentation, clarifies some

renames the API documentation generator command from gen-docs to
docs-gen to match the output binary name.
