Sdss-lvmnps

✨ Improved

* Added `all-off` command.

✨ Improved

* It's now possible to call `status` with an outlet and a summary of the status for only that outlet will be issued.

🔧 Fixed

* Issue an NPS refresh before issuing any status.

📖 Documentation

* Added section on how to use the library.

✨ Improved

* Added `NPSClient.all_off()` to turn off all outlets at once.

🔥 Breaking changes

* [36](https://github.com/sdss/lvmnps/pull/36) Complete rewrite, mostly to simplify the code and to take advantage of some additional features in the DLI REST API and to support calling DLI user scripts.
* The main difference in this version is that the code has been significantly simplified by requiring that one instance of the `lvmnps` actor can only control one NPS. This means that all the `switch` flags and parameters have been deprecated.
* The code has been simplified. It still follows the approach of a core, abstract `NPSClient` class with multiple implementations for different switches, but some options that were not used have been removed.
* It's now possible to switch multiple outlets at the same time. This takes advantage of the DLI and NetIO implementations to turn on several outlets as quickly as possible without risking an in-rush overcurrent.
* The DLI client now allows to command user functions (scripts).

🚀 New

* [34](https://github.com/sdss/lvmnps/pull/34) Add support for ``netio`` devices.

✨ Improved

* Bump `CLU` to 2.1.0.
* Various Docker image and build modifications for deployment in Kubernetes.
* Lock connections to DLI during a request.

🔥 Breaking changes

* Major update with some breaking changes. Some of the main features are:
* General clean-up, typing, linting, etc.
* A few changes to how outlets are resolved depending on whether the name or the port are provided.
* Some clean-up of the `DLI` and `DLIPowerSwitch` classes (new names). Nothing very major except that now if `ouo=False` in the configuration file, the port information is read directly from the API. This means that the outlet name is not `XXX.portN` anymore but whatever name is defined in the switch internal configuration. The default configuration for the LVM DLI switches does not specify the outlets anymore and instead reads them directly from the device.
* Converted the switches list in `NPSActor.parser_args` to a dictionary.
* For the `status`, `on` and `off` commands, changed the options and arguments. Now for `status` one can provide no arguments (all outlets are printed, as before), the switch name, the switch and port numbers, or the outlet to print.
* Removed the `reachable` command group since it was confusing. Instead, added `outlets` and `switches` commands that output the same as `reachable outlets` and `reachable switches`.
* Refactored the test fixtures a bit and increased test coverage to 85%-ish.
* Changed documentation theme and cleaned up documentation a bit.
