Migrate endpoint projects to dedicated environments

[carterm]

Drought, cannabis, & digital.ca.gov need to be moved to their own environments so that this repo (wordpress-to-github) can be the module site only.

• Create Drought FaaS service FA-GO-WORDPRESS-TO-GITHUB-DROUGHT-CA-GOV
• Create Drought FaaS repo cagov/services-wordpress-to-github-drought-ca-gov
• Migrate and test features for Drought
• Create Cannabis FaaS service FA-GO-WORDPRESS-TO-GITHUB-CANNABIS-CA-GOV
• Create Cannabis FaaS repo cagov/services-wordpress-to-github-cannabis-ca-gov
• Migrate and test features for Cannabis
• Create Digital.ca.gov FaaS service FA-GO-WORDPRESS-TO-GITHUB-DIGITAL-CA-GOV
• Create Digital FaaS repo cagov/services-wordpress-to-github-digital-ca-gov
• Migrate and test features for Digital
