Previously attempting to download LFS files with Bitbucket via a project
import would result in a 401 error. This happened because Bitbucket
returns a `header` payload that should be included in the HTTP GET
request. As described in
https://github.com/git-lfs/git-lfs/blob/main/docs/api/batch.md, we need
to include this with the request for the download to succeed.

The table merge_request_diff_commits stores the names and Emails of
commit authors and committers. This data is stored as-is. This means
that if I push 10 commits, GitLab stores my name and Email address 20
times: 10 times for the author details, and 10 times for the committer
details.

This commit adds a set of migrations and code changes to resolve this
problem. Instead of storing names and Emails for every occurrence, we'll
store a unique set of names and Emails in a separate table. The table
merge_request_context_commits in turn has two new columns:
commit_author_id and committer_id.

When creating rows for merge_request_context_commits, we take the author
and committer details and try to find an existing row in the newly
added table. If no row exists, one is created.

The resulting setup is such that given a name and Email pair of (X, Y),
we only store a single occurrence of that pair. This reduces the amount
of space necessary to store all this information. Based on our findings
in https://gitlab.com/gitlab-org/gitlab/-/issues/331823, we estimate
that over 95% of the data currently stored is duplicate data. For
GitLab.com, we estimate this will translate to roughly 500 GB of data we
no longer need to store.

The migration process for GitLab.com will likely take around two weeks,
based on our estimates discussed in
https://gitlab.com/gitlab-org/gitlab/-/issues/331823#note_595865070. The
exact time may differ based on how lucky (or not) we get, and the exact
number of rows that have to be migrated.

Changelog: performance

This commit updates the data point style on lead time graphs (both
project and group-level) to always render a blue dot. This makes it
easier to see isolated data points on the graphs.
