[site:install] Add a --db-url option

[mondrake]

Problem/Motivation

With Testing framework does not work with contributed database drivers, in Drupal 8.6.x a new set of methods has been introduced to convert DB URLs back and forth to database connection arrays.

While that's meant for testing, it would be great to enable a --db-url option for site install - the value passed in can be split by Drupal core in the relevant components without needing to pass all the separate --db-user, --db-pass etc. options.

The good thing is that it will be the same URL used to specify the value of the SIMPLETEST_DB variable in testing, so CI tools could unify on a single variable to specify installation and testing.

Example:

drupal site:install  standard  \
--langcode="en"  \
--db-url="mysql://u53rn4m3:[email protected]:3306/drupal8"  \
--site-name="Drupal 8"  \
--site-mail="[email protected]"  \
--account-name="admin"  \
--account-mail="[email protected]"  \
--account-pass="p455w0rd"

Hi @mondrake, We already implemented db-url as an argument in #3917 and #4051.

This will be available to the next release.

Great! I was watching that :)

Please see #4048 for an issue, and #4049 for a suggested improvement.

This can be closed now, I guess.
