Instead of depending on a Nextcloud test server created through Docker,
NextcloudTestServerContext now uses the NextcloudTestServerHelper
interface. This makes possible to provide other implementations of the
interface for those cases in which using a Docker container is not a
valid approach, like in the continuous integration system of the public
repository due to security concerns.

The NextcloudTestServerHelper interface provides the needed methods to
manage the Nextcloud server used in acceptance tests.

For consistency with the rest of private methods in the class,
"isContainerRegistered" is moved below the only public method in which
it is used ("cleanUp").

Mink elements (including the document element) provide a
"find(selector, locator)" method to look for child elements in their web
browser session. The Locator class is added to be able to store the
selector and locator in a single object; it also provides a fluent API
to ease the definition of Mink locators, specially those using the
"named" selector.
The method "find(locator, timeout, timeoutStep)" is added to Actor
objects; it is simply a wrapper over Mink's "find(selector, locator)"
method, although it throws an exception if the element can not be found
instead of returning null, and it also makes possible to automatically
retry to find the element for certain amount of time.

An actor plays the role of an end-user in the test scenario. As such,
each actor has its own web browser session used to perform the actions
specified by the steps of the scenario. Only one actor is active at a
time in a test scenario, and the current actor can be set through the "I
act as XXX" step; from then on, all the steps are performed by that
actor, until a different actor is set by calling "I act as XXX" again.
If no actor was explicitly set in a scenario then the default actor,
unsurprisingly named "default", is the one used.
The ActorContext class is added to provide automatic support for all
that. To use the ActorContext, besides adding it to the context list in
"behat.yml", a Mink session for each actor used in the features must be
specified in "behat.yml". Once done other Contexts just need to
implement the ActorAwareInterface (which can be done simply by using the
ActorAware trait) to have access to the current Actor object of the test
scenario; as the Actor object provides its own session other Contexts do
not need to extend from RawMinkContext. The ActorContext is itself a
RawMinkContext, so it automatically receives the base URL of the
Nextcloud test server run by NextcloudTestServerContext and propagates
that base URL to all the actors.

Scenarios in acceptance tests must be independent one of each other.
That is, the execution of one scenario can not affect the execution of
another scenario, nor it can depend on the result of the execution of a
different scenario. Each scenario must be isolated and self-contained.
As the acceptance tests are run against a Nextcloud server the server
must be in a known and predefined initial state each time a scenario
begins.
The NextcloudTestServerContext is introduced to automatically set up the
Nextcloud test server for each scenario.
This can be achieved using Docker containers. Before an scenario begins
a new Docker container with a Nextcloud server is run; the scenario is
then run against the server provided by the container. When the scenario
ends the container is destroyed. As long as the Nextcloud server uses
local data storage each scenario is thus isolated from the rest.
The NextcloudTestServerContext also notifies its sibling RawMinkContexts
about the base URL of the Nextcloud test server being used in each
scenario.
Although it uses the Behat context system, NextcloudTestServerContext is
not really part of the acceptance tests, but a provider of core features
needed by them; it can be seen as part of a Nextcloud acceptance test
library. Therefore, those classes are stored in the "core" directory
instead of the "bootstrap" directory. Besides its own (quite limited)
autoload configuration, Behat also uses the Composer autoloader, so the
"core" directory has to be added there for its classes to be found by
Behat.
