prepare all apps/flists for testcerts #608
Description
Right now some apps work with self signed certs as a fallback (e.g threebot), some fail without them (e.g publisher*)
suggest
- config param that can be configured on env e.g production
marketplace-testnet.grid.tf(testcert=False) and on stagingmarketplace-testnet2.grid.tf(testcert=True) - this gets passed to all solutions in env vars
- all apps based on nginx reverse proxy container switch the let's encrypt dest to the staging
- all apps the working with caddy should respect that env var as well
- threebot solution should support test_cert Test Cert support in 3bot solution #627
