Make sessions controller specs more explicit
Fix 2FA authentication spoofing vulnerability
Add specs for sessions controller including 2FA
Fix 2FA authentication spoofing
## Summary
This is security fix for vulnerability described at
https://gitlab.com/gitlab-org/gitlab-ce/issues/14900.
Attacker was able to bypass password authentication of users that have 2FA enabled, and consequently sign is as a different user, without knowing his password, if he managed to guess 2FA One Time Password for that user.
It was also possible to enumerate users and check if they have 2FA enabled, because GitLab responded with different error for each case.
## Fix
This MR attempts to change default user search scope if `otp_user_id` session variable has been set. If it is present, it means that user has 2FA enabled, and has already been verified with login and password. In this case we should look for user with `otp_user_id` first, before picking it up by `login`.
Both, 2FA authentication spoofing and 2FA discovery have been covered by specs.
## Further work
Current 2FA code is a bit tricky, so it probably needs some refactoring.

Only update main language if it is not already set
Related to gitlab-org/gitlab-ce#14937 (but does not fully fix) This is a temporary fix so performance isn't affected so much.
cc @yorickpeterse @ayufan how does this look?

Allow SAML to identify external users and set them as such
Related to #4009Fixes#14577
This allows SAML to retrieve group information form the `SAML Response`
and match that to a setting that will flag all matching users as external.

Wiki preview URL converting problem [via Markdown]
Current implementation when rendering the preview, thinks relative links are for project repository files.
We are creating a new preview route that will define correct context data to render for wikis instead.
Fixes#2380, #1184
See merge request !3461
Unblocks user when active_directory is disabled and it can be found
We implemented a specific block state to handle user blocking that originates from LDAP filtering rules / directory state in !2242.
That introduced a regression in LDAP authentication when Active Directory support was disabled. You could have a scenario where the user would not be temporarily found (like a filtering rule), that would mark the user as `ldap_blocked`, but will never unblock it automatically when that state changed.
Fixes#14253, #13179, #13259, #13959

Fix header link rendering when containing numbers
This fixes the problem where Markdown such as:
### 31st
Would get rendered as a link tag pointing to issue number 31 inside a
header tag.
See gitlab-org/gitlab-ce#14936 for more information.

Support for measuring Ruby blocks using GitLab performance monitoring
This adds support for measuring timings of arbitrary Ruby blocks.
Fixes#14710
See merge request !3515
This allows measuring of timings of arbitrary Ruby blocks, this allows
for more fine grained performance monitoring. Custom values and tags can
also be attached to a block.
This fixes the problem where Markdown such as:
### 31st
Would get rendered as a link tag pointing to issue number 31 inside a
header tag.
See gitlab-org/gitlab-ce#14936 for more information.
Fix Error 500 after renaming a project path
Renaming the path of a project would result in an Error 500 due to `@repository` being memoized with the old path. An Error 500 would result:
