To be able to better tackle the performance issues in
WebIDE, we need to know what we measure and what we
optimise for. This commit brings several more User Timing
metrics into the mix which the further performance work
in WebIDE should be based upon.

When saving Elasticsearch migrations we set a started_at and
completed_at value. This will help us long term with debugging as this
information will make it much easier to find relevant logs for what
happened.

As this index was not declared with [strict dynamic
mapping](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/dynamic.html)
it is totally safe to just add new fields to the payload without them
existing already in the configuration and I have tested locally that
this works as well.

For the sake of clarity, however, we have added them to the mappings as
there is no reason not to.

Update source installation to use Git from Gitaly

See merge request gitlab-org/gitlab!47613

Currently, there's quite a lot of different places which keep track
about which Git version is required by Gitaly in order to have it
operate correctly. This list is hard to keep current, and naturally
those places have diverged in the path.

To fix this, we're moving towards a single source of truth for the
current Git version, which is going to be Gitaly. To implement this,
Gitaly nowadays provides a "make git" target which automatically builds
a supported configuration of Git and installs it into the desired
location. While not yet done, the vision is that this allows us to
quickly iterate in case there are security vulnerabilities reported or
in case there's a bug in Git which impacts operations.

As a first target, this commit converts our source-based installation
instructions to use this target.
