pkg: set minimum TLS version to 1.0 (disable SSL3)

SSLv3 is no longer considered secure, and is not supported by golang
clients. Set the minimum version of all TLSConfigs that etcd uses to
ensure that only TLS >=1.0 can be used.

main: use node name as default dir
We use nodeID as the default dir previously. It works fine before we do dynamic nodeID
generation (introducing time). After the change the dynamic nodeID will change every
time we restart the etcd process. If the user does not provide the data dir, the default
dir will change every time. It is not the desired behavior.

In this commit, we change the default data dir to node name. If the user changes the node
name and does provide the data dir, etcd still cannot recover from previous state. But it
is much better than using nodeID. And it is actually a doucmentation issue.
