We default it to `true`, keeping up with upstream and the old behavior.

s3-storage-provider users may set `matrix_synapse_enable_local_media_storage` to `false`
to disable local file caching.
This likely comes at the expense of some performance.

For matrix-media-repo users, it likely doesn't matter what this is set to,
as for a matrix-media-repo setup, all media-related API endpoints are
captured and forwarded to matrix-media-repo (before reaching Synapse).

* synapse - introduce matrix_synapse_url_preview_url_blacklist var

* Preserve original comments around `url_preview_url_blacklist`

This works around an issue with Matrix Authentication Service's `syn2mas` sub-command (at version v0.16.0),
which chokes with an error:

> Error: Failed to load Synapse configuration
> Caused by:
> invalid type: found unit, expected struct EnableableSection for key "default.cas_config" in homeserver.yaml YAML file

This issue is likely to be fixed in MAS v0.16.1 or v0.17.0.

It's useless and just makes the config longer.

`auto_join_mxid_localpart` defines the local part of the user id which is used to create auto-join rooms. The variable needs to be set to invite new users to any auto-join rooms which are set to invite-only.

All homeserver implementations have been updated to support this as
well.

It's just Jitsi that possibly doesn't work with anything other than `auth-secret`.

We're casting everything it `int`, but since Jinja templates are
involved, these values end up as strings anyway.

Doing `| int | to_json` is good, but we should only cast numbers to
integer, not empty strings, as that (0) may be interpreted differently
by Synapse.

To turn of auto-tuning, one is possibly supposed to pass empty strings:

> This option defaults to off, enable it by providing values for the sub-options listed below.

It could be that `0` is also considered "no value provided", but I
haven't verified that.
