Updated the TLS configuration.
...
This commit removes support for the TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA and TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA ciphers. It also removes support for CurveP384. This is to match up with recommendations given by Cloudflare [0], Mozilla (the "Intermediate" compatibility) [1], and referencing the default ciphers in Caddy [2].
