Addition of Grow Properties for Plant Profiles, and ability to add Plant Data

[StevonStevoff]

Lots of changes in this PR, sorry probably should have broken it up a little.

Main changes:

• Added Grow Properties
  • Types are managed in a separate route only editable by admins
  • Grow Properties themselves contain the desired ranges for a plant's data
• Added ability to create plant data
  • Currently the device identification is simply by passing the device ID - this will allows manual testing on the API, we will sort the proper device auth later.
  • You can see how this is created by looking at the swagger docs, you can have any number of sensor readings per plant data object, provided they are for a valid sensor.
  • Currently the timestamp is for a single plant data object, however we could change this to be per individual sensor reading depending on desired behaviour on device itself.
  • Note: Plant data can be read via the plant route: /plant/{id}/data

Additional changes:

• Updating tests to cope with new additions (have not created new unit tests for the actual routes though)
• Added grow duration to Plant Profiles
• Added Plant Location (latitude, longitude) and Indoor marker to Plant objects
