Network: total bytes of incoming and outgoing server's data
by taking advantage of our ConnMux Read/Write wrapping
HTTP: total number of different http verbs passed in http
requests and different status codes passed in http responses.
This is counted in a new http handler.
For TLS peekProtocol do not assume the incoming request to be a TLS
connection perform a handshake() instead and validate.
Also add some security related defaults to `tls.Config`.
This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.
This also fixes `goconst ./...` reported issues.
EOF err message in Peek Protocol is shown when a client closes the
connection in the middle of peek protocol, this commit hides it since it
doesn't make sense to show it
rpcClient should attempt a reconnect if the call fails
with 'rpc.ErrShutdown' this is needed since at times when
the servers are taken down and brought back up.
The hijacked connection from net.Dial is usually closed.
So upon first attempt rpcClient might falsely indicate that
disk to be down, to avoid this state make another dial attempt
to really fail.

Default golang net.Listen only listens on the first IP when
host resolves to multiple IPs.
This change addresses a problem for example your ``/etc/hosts``
has entries as following
```
127.0.1.1 minio1
192.168.1.10 minio1
```
Trying to start minio as
```
minio server --address "minio1:9001" ~/Photos
```
Causes the minio server to be bound only to "127.0.1.1" which
is an incorrect behavior since we are generally interested in
`192.168.1.10` as well.
This patch addresses this issue if the hostname is resolvable
and gives back list of addresses associated with that hostname
we just bind on all of them as it is the expected behavior.
Adding deadlines is a no go since Golang doesn't back off
the timers if there is an active i/o in progress.
It is meant to be for applications to handle this themselves
and manually progress the deadlines.
Fixes#2561
