Revision 0.0.3, released XX-04-2020#

Modified Management REST API not to report tag information (esp. the whole lot of tagged objects) on tag update calls.
Rebuild SNMP simulator invocation script only on Lab power state change for performance reasons. Prior to this change, invocation script has been generated on every change in the DB. This was causing unnecessary SNMP simulator restarts and REST API server slowness.
Add tox runner with some basic jobs.
Fix SQL/ORM problem in SNMP Simulator invocation script generation that manifested itself as extreme slowness with the increasing number of powered on labs.

Added SNMP simulator processes runtime metrics collection by the supervisor process. Gathered information is stored in the DB and served via newly introduced REST API endpoints.

Added PUT /snmpsim/mgmt/v1/recordings/<recording> endpoint which (unlike POST) will create new or override existing recording.
When creating new recordings, also create all directories leading to the recording being created. When recording is deleted, try to also remove its directory if it’s empty.
Fixed WSGI servers default config initialization.
When failing to create/override a recording, return HTTP code 490 instead of 404.
Added example systemd unit files for all control panel components.
Renamed REST API specs into snmpsimd-mgmt and snmpsim-metrics on Swagger and moved spec files into specs folder.
Removed SQL cascading from all management API models. That makes SNMP simulator entities less dependent from each other when deleting some of them what facilitates their reuse.
Added a new feature of tagging to Management API. Every Management API object can be tagged with zero or more tags. The REST API client can then obtain all tagged objects at once searching by tag.
