i_add_enrolment_method_with() is now deprecated, please use
i_add_enrolment_method_for_with() instead.

This creates new general behat steps for navigating in theme
boost and classic.

The focus should be on something, rather than removed.

The way in which focus removal works can lead to side effects.

Definition step deprecated and affected tests modified.

Fixes for the new enrol users popup with behat.

The add/roles thing was only converted to bootstrap 2/4 markup and the yui left in place.

The modal for adding users to a course was unsavable so I rewrote it with an mform in a popup, still calling
the same (barely) modified ajax script.

The webservice for searching cohorts was taken from admin/tool/lp and moved into /cohort. I added a generic "cohort"
mform element at the same time.

The webservice for searching for users was taken from the original ajax script.

During the recent reimplementation of the step (eb9ca848), we did not
notice that javascript variant uses the string `assignroles` while the
non-js variant uses string `assignrole`. This caused any "Given I enrol"
steps to fail in non-javascript sessions.

xpathLiteral has been depreacted, use Escaper instead

Behat 3.x doesn't support chained steps and hence
this is first step to get rid of chained steps in core.

- MDLQA-6: By default, a new course contains a news
forum in which only teachers can post and subscription
is forced

The following used steps were replaced by the ones
added in this issue:
- I fill the moodle form with
- I fill in with
- I select from
- I select radio button
- I check
- I uncheck
- the field should match

Also removing test for deprecated steps:
- the ASD checkbox should be checked
- the ASD checkbox should not be checked

- Escaping steps arguments redirected to other steps
- Adding normalized-space() in all contains() assertions
- General xpaths review
- Convering provided xpath text strings to xpath literals
  to avoid problems with arguments containing both single
  quotes and double quotes

Using get_string() instead.

Moving from phpunit test environment
to a specific behat test environment
