use PHP 8.0 image for master integration tests

[blizzz]

• depends on Add new image for user_saml_shibboleth-php8.0 docker-ci#359

Tests are still not stable, and sometimes fail with:

[18/Mar/2022:15:20:22.704103023 +0000] - ERR - add_new_slapd_process - Unable to start slapd because it is already running as process 9
[18/Mar/2022:15:20:22.705794092 +0000] - CRIT - main - Shutting down due to possible conflicts with other slapd processes

However there is nothing that would start the same thing twice. I even removed the start.sh as CMD from the dockerfile in nextcloud/docker-ci#359, without effect. I thought for a weird reason it could be dependent on the host system (some workers are still on Ubuntu 18.04), but when doing it manually i could not reproduce it. Nor can i locally.

@blizzz I searched online for that message, and found this: https://pagure.io/389-ds-base/issue/50989

are we stopping and restarting that service repeatedly ? maybe some lock cleanup missing ?

[PVince81]

ok, so it seems there's a solution already: nextcloud/docker-ci#359 (comment)

[PVince81]

I've restarted the build and hope it will pick up the change there

Solution seems to work 🎉
Applying it to 8.0, rebuilding images

Remove vendor files?

Remove vendor files?

sheesh, that opened another pandora's box

[blizzz]

Mh, I am feeling to split the last commit from here and unifiy 3rdparty and vendor. Otherwise people will be mad to install it for it has to be composer install twice. This does not need to be another blocker.

@artonge vendor file removal at #594
