Use clock_gettime for all performance timestamps

This MR adjusts the performance monitoring code to use `Process.clock_gettime` (thus `clock_gettime(3)`) instead of `Time.now`.

Using `Time.now` / `Time.new` adds more overhead than `Process.clock_gettime`, it also doesn't provide a way of getting timestamps in nanoseconds (which `Process.clock_gettime` does allow).

Fix an information disclosure when requesting access to a group containing private projects

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/19102.

The commit speaks for itself:

    Fix an information disclosure when requesting access to a group containing private projects
    
    The issue was with the `User#groups` and `User#projects` associations
    which goes through the `User#group_members` and `User#project_members`.
    
    Initially I chose to use a secure approach by storing the requester's
    user ID in `Member#created_by_id` instead of `Member#user_id` because I
    was aware that there was a security risk since I didn't know the
    codebase well enough.
    
    Then during the review, we decided to change that and directly store the
    requester's user ID into `Member#user_id` (for the sake of simplifying
    the code I believe), meaning that every `group_members` / `project_members`
    association would include the requesters by default...
    
    My bad for not checking that all the `group_members` / `project_members`
    associations and the ones that go through them (e.g. `Group#users` and
    `Project#users`) were made safe with the `where(requested_at: nil)` /
    `where(members: { requested_at: nil })` scopes.
    
    Now they are all secure.

Use jQuery objects in ref dropdown

## What does this MR do?

Keeps the behaviour the same as the ref dropdown, however it now uses jQuery objects to handle the HTML creation instead of passing strings around. It pretty much worked out the box so not much was changed in the dropdowns themselves. Will be easy to transfer this over to other dropdown menus as well.
