Add option to disable DNS ACME provider (#290)

This PR add the `$NO_DNS_01` option (disabled by default) that removes the DNS ACME provider, and replaces the wildcard certificate by individual certificates obtained using the TLS ACME provider.

This option allows an instance to work without having to manage access tokens for the DNS provider. On the flip side, this means that a certificate can be requested for each subdomains. To limit the risk of DOS, the existence of the user/org corresponding to a subdomain is checked before requesting a cert, however, this limitation is not enough for an forge with a high number of users/orgs.

- `ENABLE_HTTP_SERVER` (default: false): Set this to true to enable the HTTP-01 challenge and redirect all other HTTP requests to HTTPS. Currently only works with port 80.
- `DNS_PROVIDER` (default: use self-signed certificate): Code of the ACME DNS provider for the main domain wildcard.
See <https://go-acme.github.io/lego/dns/> for available values & additional environment variables.
- `NO_DNS_01` (default: `false`): Disable the use of ACME DNS. This means that the wildcard certificate is self-signed and all domains and subdomains will have a distinct certificate. Because this may lead to a rate limit from the ACME provider, this option is not recommended for Gitea/Forgejo instances with open registrations or a great number of users/orgs.
- `LOG_LEVEL` (default: warn): Set this to specify the level of logging.
