FEMS Backports (#1658)

- Improvements for Time-Of-User Tariffs (#162)
  - Implement generic  Time-of-Use tariff service.
  - Implement Awattar TOU tariff provider implementation.
  - Implement Corrently by STROMDAO TOU tariff
- Checkstyle: do not required Javadoc for build() method in builder pattern
- Add System-Update feature (if OpenEMS Edge is installed via Debian package)
  - Add ExecuteSystemUpdateRequest and GetSystemUpdateStateRequest
- Add Password-only sudo authentication for system execute
- Add `exitcode` to ExecuteSystemCommandResponse
- Add global .gitignore patterns
- Update gradle bnd version to 6.0.0
- Increase number of Threads in ThreadPools to avoid pending tasks
- Add handling of BundleContext in activate (without DummyBundleContext, because that had caused Resolve errors)
- UI: improve detection of isOnline
- Set default port 8085 in edge-dev.ts
- TypeUtils: fix conversion from Double to Float
  - This fixes a bug where a double "0.0" could not be converted to float, with following error: "Cannot convert. Double [0.0] is not fitting in Float range."
  - Also applied Checkstyle on TypeUtils.
- Keba KeContact: trim configured IP address
  - This avoids "evcs0[Failed activation java.net.UnknownHostException: xxx.xxx.xxx.xxx]
- Introduce OpenemsOEM class which simplifies creating custom distributions of OpenEMS
- Soltaro Battery Improvement
- Sinexcel Battery Inverter New Modbus Protocol Implementation
- Allow SymmetricEss in EvcsClusterPeakshaving
  - EvcsClusterPeakshaving was not able to start with a SymmetricEss like Fenecon Dess. (No Reference for component ess0 ...)
- UI register: Remove zip validator
  - Austria has only 4 digits; other countries... who knows?!
- PQ Plus UMD96 Meter Implementation
- Remove Predictive Delay Charge Controller
  - It was replaced by the more advanced "ESS Grid Optimized Charge" Controller (io.openems.edge.controller.ess.gridoptimizedcharge).
- Hardy Barth Salia: implementation improvements
  - Small things like heartbeat were changed in the hardy barth software especially for the newer salia cpµ pro 2 (single charger).
  - Another problem was the external meter that is used internally in the hardy barth to provide the current charge values.
  - This meter also measures the standby consumption of the salia itself and is disabled by default - The function to enable it automatically is on hold for now, as we need a proper update process first.
- GoodWe: add missing Write-Registers
