And update the spec tests for the latest changes

For validating the contents passed to ldap write

Use gitlab-rake for the rake commands, and always refer to LDAP in
uppercase

Rather than falling back to the `editor` binary, which is often only on
debian systems if an alernative editor was installed.

- Autogenerate the encrypted key but only when requested
- Generate the new key as part of the secret token initializer
- Add additional config check during ldap secrets edit
- Ensure that the provided input is valid yaml, and is a hash

-Ensure we creation our tempfile within our final directory
- Add encrypted settings config to gitlab.yml.example
- Update missing key syntax
- And check early for missing key during the edit command
- Ensure spec tests are rails rooted

Adds a new ldap_secrets path setting for optional ldap secrets file.
And adds a new set of ldap secrets rake commands for showing/editing an
ldap secret

Adds support for loading ldap servers' password and/or user_bn from the
encrypted secrets.

As part of initial rollout we don't want to complain about secrets for
an optional feature.

From `enc_settings_key_base` to `encrypted_settings_key_base`

This adds:

- Path for storing encrypted settings in config
- optional base token generation
- Additional error handling for missing config and keys

- Generates a new key or correct length pased on the provided base key
- Updates the naming of the key param passed to EncryptedConfiguration
- Adds tests for key length to the spec tests

Increase cipher to 256

The 128 was the default from upstream configuration encryption but
is lower then the message encryptor default. Not sure why, so we
might as well go with the larger one.

- Adds support for a new (optional) secret key from secrets.yml
- Adds a encrypted configuration class than can decrypt/encrypt files
  using the provided key
- Adds a new encrypted setting helper method to Settings for the new
  secret key

Update issues in ES when project visibility settings change

See merge request gitlab-org/gitlab!47007

Ensure changes to project visibility settings also update the associated
issue documents for that project. This is required to keep the issue
documents updated once the visibility permissions are stored within
the issue document in preparation for global search joins being
removed from the Elasticsearch issue query.

Use stricter typed global IDs for iterations

See merge request gitlab-org/gitlab!47045

Also accept a global id when querying the `iterations`
field

But maintain backward compatibility by accpeting
a raw model id
