Disable host and endpoint reporting in Kubernetes cluster mode

When the probe is run with --probe.kubernetes.role=cluster, disable
host reporting and endpoint reporting since it duplicates what is
being done by the per-host probe.

Also, extracts strings into constants

When we receive an endpoint address without a protocol, our code states we
don't support them and that the format is deprecated.

In reality it was not the case, e.g:

When we received an address in the form of `127.0.0.1`, we'd attempt to
parse the scheme from it, we'd realise is does have one (would be
equivalent to "") and our function `parseEndpoint` would return `"", "", fmt.Error`.

Then, our `parseEndpointWithFallbackProtocol` would use the
fallback protocol (unix) and attempt to connect to `unix://127.0.0.1`.

This meant two things:

1. The error returned from `parseEndpoint` would never be thrown
2. We would connect anyways since the address is valid

This commit changes the assertion logic to match the intention of using
a fallback protocol when one is not supplied.

Unhappy path tests try to cover three scenarios:

- When the endpoint URL scheme is not explicitly supported e.g. HTTP
- When the endpoint URL scheme is TCP which is also not supported
- When the fail to parse the given URL (to extract the scheme)

The happy path covers two scenarios:

- When we specify the supported scheme in the URL which is an unix
socket e.g. unix///var/run/dockershim.sock
- When we pass a socket address but fail to specify the scheme but our registry attempts
to use the fallback protocol e.g. var/run/dockershim.sock

In multitenant app, drop all nodes for big topologies

Add  LICENSE info to README.md

Fix typo

client: update stopped container message

Fix sentence meaning according to [https://github.com/weaveworks-plugins/scope-http-statistics plugin page:  "it has a negligible performance toll"

update help section

Add Satyam Zode as maintainer

* Pass Go context down to Renderers

This is useful for cancellation or tracing.

* Add tracing spans to app

Also log things like number of nodes in Map, total number of reports.

- Change apigroups to apiGroups in cluster-role.yaml
- Change resourcenames to resourceNames in cluster-role.yaml
- Add selector in deploy.yaml and ds.yaml
