Export experiment results

[litalmason]

Description

Allow exporting Test Suite results, with all its 'Test-Runs', to a file.

• Export results to JSON and/or CSV files to allow further analysis
• Optional: Export results to PDF (Table, Graphs) for management reports, etc.

JSON example:

{ 
   "id": 1, 
   "name": "test1", 
   "description": "test1", 
   "start_time": "Thu, 14 Dec 2023 15:37:31 GMT", 
   "end_time": "Thu, 14 Dec 2023 15:38:39 GMT", 
   "environment_info": { 
     "codeRelease": "1.1.0", 
     "cpu": "RELACE_WITH_CPU", 
     "cpuArchitecture": "RELACE_WITH_CPU_ARCHITECTURE", 
     "cpuClockSpeed": "RELACE_WITH_CLOCK_SPEED", 
     "cpuCores": 0, 
     "nodeSize": "RELACE_WITH_NODE_SIZE", 
     "operatingSystem": "RELACE_WITH_OPERATING_SYSTEM", 
     "resourceName": "RELACE_WITH_RESOURCE_NAME" 
   }, 
  "testRuns": [ 
    { 
      "algorithm": "Algorithm1", 
      "iterations": 1000, 
      "messageSizeBytes": 1024, 
      "results":  
        { 
      "averageCPU": 25.5, 
      "averageMemory": 512, 
      "errorRate": 0.05, 
      "bytesThroughput": 2048000, 
      "messagesThroughput": 500, 
      "averageTLSHandshakeTime": 10.2 
	} 
    } 
   ... 
  ] 

Acceptance Criteria

1. Export button in Qujata Portal
2. Export to CSV file
3. Export results as JSON file (optional for 1.1.0 milestone)
4. Export results and graphs to PDF, in a similar format to their presentation on the UI, as a ready made report you can immediately share (nice to have for 1.1.0 milestone)
5. Testing: ensure all fields are exported to CSV (native format is JSON), Titles are written in plain English, no issues with larger result files

Tasks

• Saving Test Run results in db
• Getting Test Run results from cAdvisor
• New API to export data by test_suite_id (DB & Prometheus)
• Query prometheus (CPU and memory, client and server) according to test run start/end time and aggregate to avg result
• UI changes: add button to export data according to design
• Add get API for test suites and test runs (one Test Suite includes 1 or more Test Runs)
