document docker parameter and use random host port
fix typo
copy autotest.sh to autotest-external.sh
adds ability to add start* and stop* scripts in env in external tests
run files_external WebDAV tests against ownCloud instance
introduce executor number to be able to shut down the correct docker container
fetch docker images in advance - this also fetches latest versions of the docker images
add second argument to autotest-external.sh which can specify a single test to run
print out the explicit test run
change naming schema of files_external setup scripts
To make it possible to use the short ownCloud URL (without specifying
webdav.php or remote.php), a new backend is available for ownCloud.
The user must specify the host + context path in the "Url" field (which
is mapped to the "host" parameter) and the subdir to mount in the "Root"
field.
This is to prevent confusion because some users forget to append
webdav.php or remote.php to the WebDAV URL.
Fixes#4923
