[CVE-2020-15114, CVE-2020-15136, CVE-2020-15115] Vulnerabilities in the etcd package

[SVilgelm]

There are 3 vulnerabilities in etcd package. I know that the etcd is a transitive dependency, but the viper should update the crypto package as soon as it's updated.

Here is the issue in crypto repo: bketelsen/crypt#9
