Fix http timeout for Consul check for servers

Don't fail other tasks when retrying artifact get

Update install of Vault

Web task should run to completion successfully while the `bad` task is

as dead.

Fixes #1558

Monitor the complete alloc directory, not just the shared part.

Don't duplicate TaskKilled event and check for TaskSiblingFailed.
