Consul Agent exits silently

[johscheuer]

Overview of the Issue

The consul agent fails silently if the data-dir doesn't exists or is readonly.

Reproduction Steps

Steps to reproduce this issue, eg:

Run the following commands:

$ docker run -ti --read-only consul:latest consul agent --data-dir=/tmp --log-level=TRACE
==> Starting Consul agent...

$ docker run -ti  consul:latest consul agent --data-dir=/tmpa --log-level=TRACE
==> Starting Consul agent...

The agent never tells what happened and why it crashed (even we se the log level TRACE).

Consul info for both Client and Server

None, happens directly when starting the agent wit the flags from above.
