The performance of the auto-redeploy executions configured in Maven have
been improved by adjusting the directories watched by the plugin
responsible for the redeployment.

Tests that are not fundamental have been removed.

The @angular/cdk library was not updated when the other Angular
libraries were updated. This commit fixes this by updating this
library.

The POM and other configuration files have been updated to support a new
execution mode where Cargo is used to execute the backend and NPM to
execute the frontend, both in auto-redeploy mode.

Acceptance tests were not working as they wasn't adapted to the Angular
framework after the migration. This commit fixes these test that now
work again.

Angular version has been upgraded to 8.2. In addition, "npm audit fix"
has been run to fix any security issue.

A bug was causing the "Limpiar" button of the people view not to work,
as the event-managing method was calling itself. This bugfix solves this
problem by changing the method called by the event-managing method.

The auto-redeploy mode now ignores node_modules, as it slows excesively
down the execution.

The PeopleResourceTests now include security tests to verify that normal
users can't access people data.

The example done for JavaScript, were people can be managed, has been
migrated to Angular.
