Add changelog

This python implementation of a tap formatting library for buildkite has been
replaced with a perl implementation as part of the matrix-org/sytest repo,
which is specific to sytest's language, not that of any one homeserver's.

This is all for dendrite really.

-Synapse 1.7.0 (2019-12-13)
-==========================
-
-This release changes the default settings so that only local authenticated users can query the server's room directory. See the [upgrade notes](UPGRADE.rst#upgrading-to-v170) for details.
-
-Support for SQLite versions before 3.11 is now deprecated. A future release will refuse to start if used with an SQLite version before 3.11.
-
-Administrators are reminded that SQLite should not be used for production instances. Instructions for migrating to Postgres are available [here](docs/postgres.md). A future release of synapse will, by default, disable federation for servers using SQLite.
-
-No significant changes since 1.7.0rc2.

 All Matrix projects have a well-defined code-style - and sometimes we've even
 got as far as documenting it... For instance, synapse's code style doc lives
-[here](docs/code_style.md).
-
-To facilitate meeting these criteria you can run `scripts-dev/lint.sh`

-
-```
-# Install the dependencies
-pip install -U black flake8 isort
-
-# Run the linter script
-./scripts-dev/lint.sh
-```
-
-**Note that the script does not just test/check, but also reformats code, so you
-may wish to ensure any new code is committed first**. By default this script
-checks all files and can take some time; if you alter only certain files, you
-might wish to specify paths as arguments to reduce the run-time:
-
-```
-./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
-```
-
-Before pushing new changes, ensure they don't produce linting errors. Commit any
-files that were corrected.
+at https://github.com/matrix-org/synapse/tree/master/docs/code_style.md.
 
 Please ensure your changes match the cosmetic style of the existing project,
 and **never** mix cosmetic and functional changes in the same commit, as it
 makes it horribly hard to review otherwise.

-Upgrading to v1.7.0
-===================
-
-In an attempt to configure Synapse in a privacy preserving way, the default
-behaviours of ``allow_public_rooms_without_auth`` and
-``allow_public_rooms_over_federation`` have been inverted. This means that by
-default, only authenticated users querying the Client/Server API will be able
-to query the room directory, and relatedly that the server will not share
-room directory information with other servers over federation.
-
-If your installation does not explicitly set these settings one way or the other
-and you want either setting to be ``true`` then it will necessary to update
-your homeserver configuration file accordingly.

-Upgrading to v1.5.0

-complete if there are a large number (more than a million or so) of entries in
-the ``devices`` table. This is only likely to a be a problem on very large
