Add project as input

[mmacata]

This PR changes how the GRASS GIS project in which to run the process can be defined.
We do not stick to the convention introduced in actinia-org/actinia-module-plugin#64 (project name must be set in template). Instead a default project is configured which can be overwritten as input at process execution. This input is also added to each process description.

Example for process description

{
  "categories": [
    "actinia-module",
    "global-template"
  ],
  "description": "Imports point and polygon and checks if point is in polygon.",
  "id": "point_in_polygon",
  "parameters": [
    {
      "description": "The input source that may be a landsat scene name, a sentinel2 scene name, a postGIS database string, or an URL that points to an accessible raster or vector file [generated from import_descr_source]",
      "name": "url_to_geojson_point",
      "optional": true,
      "schema": {
        "type": "string"
      }
    },
    {
      "description": "Name of GRASS GIS project to use",
      "name": "project",
      "optional": false,
      "schema": {
        "type": "string"
      },
      "default": "nc_spm_08"
    }
  ],
  "projects": [
    "nc_spm_08"
  ],
  "returns": []
}

Processing Examples

Project given as input

{
  "inputs": {
    "url_to_geojson_point": "https://raw.githubusercontent.com/mmacata/pagestest/gh-pages/pointInBonn.geojson",
    "project": "nc_spm_08"
  },
  "outputs": {
    "result": {
      "transmissionMode": "reference"
    }
  },
  "response": "document"
}

Will lead to HTTP POST to "http://actinia-core:8088/api/v3/projects/nc_spm_08/processing_export"

Non exiting project given as input

If the project does not exist, it will return

{
    "processID": "resource_id-7d04d408-c98e-4c7a-becf-3d4392e01d05",
    "type": "process",
    "jobID": "7d04d408-c98e-4c7a-becf-3d4392e01d05",
    "status": "failed",
    "message": "GrassInitError:  Error while executing the grass module.              The following error message was logged:\nERROR: MAPSET PERMANENT not found at /actinia_core/workspace/temp_db/gisdbase_083533fc70cb4cb5b4a2d4ad2697a069/nc_spm_088\n",

        "rel": "self"
    }
    ]
}

No project given as input, default is used

If no project is given, the default project will be used (configurable).

Looks good to me, thanks.
Maybe just think about reasonable tests for new project parameter?

[mmacata]

I added one test - the different usage of project per config or per input parameter is not directly visible, but now the file src/actinia_ogc_api_processes_plugin/core/process_execution.py has a coverage of 100% and the content of if condition is also tested:

     if postbody.get("inputs").get("project"):
        project_name = postbody.get("inputs").get("project")
