HRQB 18 - Data warehouse and Quickbase connection tests

[ghukill]

Purpose and background context

This application requires connectivity to the Data Warehouse and Quickbase. A dedicated CLI command for testing those connections is helpful for debugging environments in Dev, Stage and Prod.

How this addresses that need:

• Adds test_connection() method on DWClient and QBClient classes
• Adds CLI command test-connections that runs this method and logs output

How can a reviewer manually see the effects of these changes?

Set invalid credentials as local env vars:

WORKSPACE=dev
SENTRY_DSN=None
DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH
LUIGI_CONFIG_PATH=hrqb/luigi.cfg
QUICKBASE_API_URL=https://api.quickbase.com/v1
QUICKBASE_API_TOKEN=qb-api-acb123
QUICKBASE_APP_ID=qb-app-def456
DATA_WAREHOUSE_CONNECTION_STRING=bad-protocol://user1:pass1@example.org:1521/ABCDE

Run CLI command:

pipenv run hrqb --verbose test-connections

Note the output that both DW and QB connections fail. If both successful, would see "All connections OK" in logs.
