Quay Config Editor should make sure latest SSL_PROTOCOLS are applied in configuration

Problem :

• If SSL_PROTOCOLS was manually set to TLSv1.2 in the past, in the latest versions of quay, config-editor will not add TLSv1.3 unless old configurations are changed manually.
• Quay config-editor tool does not add ssl related configurations to config.yaml or add latest available values to those configuration fields.

$ grep SSL config.yaml 
$ grep -i SSL config.yaml 
$ grep -i TLS config.yaml 
EXTERNAL_TLS_TERMINATION: true
MAIL_USE_TLS: false
REPO_MIRROR_TLS_VERIFY: true

Expectations:

• Set default value of SSL_PROTOCOL to latest protocol available. Eg: TLSv1.3
• Option to set SSL_PROTOCOL from quay-config-editor. Give customer an option to use TLSv1.2 or TLSv1.3
• Editor-tool should add SSL configurations + default values to its generated config.yaml file
• Have a warning message and inform the user that TLSv1.3 latest protocol is not being used and they can add it.
