EOSdash: Improve PV forecast configuration. (#500)

* Allow to configure planes and configuration values of planes separatedly.

Make single configuration values for planes explicitly available for configuration.
Still allows to also configure a plane by a whole plane value struct.

* Enhance admin page by file import and export of the EOS configuration

The actual EOS configuration can now be exported to the EOSdash server.
From there it can be also imported. For security reasons only import and export
from/ to a predefined directory on the EOSdash server is possible.

* Improve handling of nested value pathes in pydantic models.

Added separate methods for nested path access (get_nested_value, set_nested_value).
On value setting the missing fields along the nested path are now added automatically
and initialized with default values. Nested path access was before restricted to the
EOS configuration and is now part of the pydantic base model.

* Makefile

Add new target to run rests as CI does on Github. Improve target docs.

* Datetimeutil tests

Prolong acceptable time difference for comparison of approximately equal times in tests.
