Add TLS min/max configuration

[otolizz]

Hello,

Is there a way to force influxdb-relay to communicate in tls1.2 minimum?
It would be nice to have a configuration like the one in influxdb:
[tls] ciphers = [ "TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305", "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256", ] min-version = "tls1.2" max-version = "tls1.2"

Hi, sorry it's not available yet but it could be a feature improvement.

We could take kapacitor source-code as an exemple https://github.com/influxdata/kapacitor/blob/master/tlsconfig/config.go

It would be great if you could add it in the next version :)
