Rewrite of generate-environment-identifiers-dict.sh

**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More lists recommendations would be appreciated as these lists may be outdated.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
- [x] I intend to open a pull request later
