fix skype bridge being rebuilt when upstream changed

No migration steps should be required.

This should be a no-op, no migration necessary.

Ansible will migrate the ownership of the base path and config path, but
manual intervention will be required in order to migrate the ownership
of files in those directories (i.e. dimension.db).

Stop the services:

  (local)$ ansible-playbook -i inventory/hosts setup.yml --tags=stop

Fix the permissions on the server:

  (server)# chown -Rv "{{ matrix_user_username }}:{{ matrix_user_username }}" "{{ matrix_dimension_base_path }}"

which would typically look like:

  (server)# chown -Rv matrix:matrix /matrix/dimension/

Reconfigure Dimension and start the services:

  (local)$ ansible-playbook -i inventory/hosts setup.yml --tags=setup-dimension,start

Architecture

FIXME: horrid duplication in template file

· 😅 How to keep this in sync with the matrix-synapse documentation?
· regex location matching is expensive
· nginx syntax limit: one location only per block / statement
· thus, lots of duplicate statements in this file

· needs documentation; no checks yet for port clashes or typos in worker name
· according to https://github.com/matrix-org/synapse/wiki/Workers-setup-with-nginx#results
  about 90% of requests go to the synchrotron endpoint
· thus, the synchrotron worker is especially suited to be load-balanced
· most of the other workers are documented to support only a single instance
· https://github.com/matrix-org/synapse/blob/master/docs/workers.md

Update nginx (1.17.9 -> 1.17.10)
