Issue:
add postgres/mysql tests to Actions
from https://github.com/cloudflare/cfssl/blob/bea2d3db90fe13a9d4c220a9ef506a82af4b1b9f/.travis.yml
spinup dbs:
```
 make bin/goose;
psql -c 'create database certdb_development;' -U postgres;
./bin/goose -path certdb/pg up;
mysql -e 'create database certdb_development;' -u root;
mysql -e 'SET global sql_mode = 0;' -u root;
./bin/goose -path certdb/mysql up;
```

run tests with `BUILD_TAGS="postgresql mysql"` and they automatically use the db

Pull request description:
