"Initialization failed" on teleport start

[kontsevoy]

Problem

This is a regression. Something changed in the error handling on teleport daemon start-up so it's masking true errors now.

Before:

$ teleport start
mkdir /var/lib/teleport: permission denied

Now (Teleport v3.1.0-alpha.4 git:v3.1.0-alpha.4-224-g7b84e5d7):

# WTF
$ teleport start
error: initialization failed

# Only a developer would know to run this:
$ teleport start -d
ERROR REPORT:
Original Error: *os.PathError mkdir /var/lib/teleport: permission denied

User Message: initialization failed

Solution

"initialization failed" thing must go away completely. It hides the true errors and is 100% not helpful. We must be losing users who're trying Teleport for the first time without even knowing it.
