Non-locked accessors to common Node fields
...
This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.

Fix invalid CPU stats on Windows
...
This PR fixes an issue introduced in Nomad 0.6.0 due to
https://github.com/shirou/gopsutil/issues/420 . The issue arised from the
fact that the Windows stats from gopsutil reports CPUs in
percentages where we expected ticks.
