[DX] Add note about Gitlab specific settings

[benr77]

I have been hunting down an issue that was killing the performance of our apps. I saw our logs were full of 401 errors from Gitlab when Unleash was trying to register the client.

I then saw in the default config of this bundle the following lines:

  # Whether to allow sending feature usage metrics to your instance of Unleash, set this to false for GitLab
  metrics_enabled:      true

  # Whether to allow automatic client registration on client initialization, set this to false for GitLab
  auto_registration:    true

Setting both these to false has immediately fixed the performance issues, and the log is no longer filled with 401 errors.

So, these settings have a big impact, and yet the note about disabling for Gitlab is buried right down at the bottom of the README and this is really easy to miss.

Can I suggest a prominent note in the top section of the README to prevent other Gitlab users falling into the same trap? Thanks

Please add a suggestion in the Readme, we don't have explicit support for Gitlab
