Rewrite of generate-environment-identifiers-dict.sh

[molangning]

Describe the feature request:
The current script uses majestic's domain list, which may be missing a lot more domains as compared to the other lists in the checklist. Another issue that I find with it is that it makes a new (insecure) ssl session for every domain in the list, which is both insecure and inefficient.

More lists recommendations would be appreciated as these lists may be outdated.

Additional context:
You can use this command to interact with the sql server directly
psql -h crt.sh -p 5432 -U guest certwatch

Next steps:

• Implement a script that pulls domains from domcorp, alexa, cloudflare, majestic and others
• Dedupe the list/find better ways to extract environment ids
• Change to use sql interface
• I intend to open a pull request later
