Minimum TTL (30) not accepted by Cloudflare API

[cotton105]

Describe the bug
Setting the TTL in the config to anything below 60 for a non-Enterprise account causes the Cloudflare API request to fail, with error code 9021:

😡 Error sending 'POST' request to 'https://api.cloudflare.com/client/v4/zones/***/dns_records':
{"result":null,"success":false,"errors":[{"code":1004,"message":"DNS Validation Error","error_chain":[{"code":9021,"message":"TTL must be between 60 and 86400 seconds, or 1 for Automatic."}]}],"messages":[]}

To Reproduce
Steps to reproduce the behavior:

1. Change the ttl option in config.json to 30 (using a non-Enterprise Cloudflare account).
2. Run python cloudflare-ddns.py --repeat.
3. See error.

Expected behavior
The TTL option should be set to 1 (auto), instead of continuing to try to use the invalid TTL in a POST request.

This is the expected behavior. Because Cloudflare does not accept less then 60 TTL

see error message TTL must be between 60 and 86400 seconds
