feat: custom domain name

[jjfrench]

• adds logic to create custom domain names for stac-api, titiler-pgstac-api, and stac-ingestor-api
• for custom domain names to be deployed, the following environment variables must be defined before deployment : CERTIFICATE_ARN (the ARN of the certificate to be used for the domain name), INGESTOR_CUSTOM_DOMAIN_NAME (if missing, no domain name will be created for the ingestor API), STAC_API_CUSTOM_DOMAIN_NAME (if missing, no domain name will be created for the STAC API) and TITILER_PGSTAC_API_CUSTOM_DOMAIN_NAME (if missing, no domain name will be created for the titiler pgstac API)
• there must be route53 records pointing to each custom domain names created here. Those records are not created here, so they must be manually updated every time the custom domain names are re-created (because their regional domain name changes).

This was deployed locally to the test environment with the main branch of eoapi-cdk and it's breaking the titiler pgstac. https://titiler-pgstac-api.dit.maap-project.org/docs gives Internal Server Error. Logs from the AWS console :

By locally deploying with eoapi-cdk main we incorporated this change developmentseed/eoapi-cdk#61, that significantly bumps titiler-pgstac and changes a little bit the handler, I strongly suspect this is the cause.

I think I found the bug, I am going to try to redeploy to test with a fix right now

I was also unable to create the ingestor domain name when deploying locally. I fixed this bug and the other one I mentioned (titiler-pgstac broken) in developmentseed/eoapi-cdk#63.

I am not approving this yet, as we need to change the import statement once the eoapi-cdk PR is merged.
