Under high load, etcd /health check QGET times out occasionally.
This has been observed during IPsec enabled system deployment when
controller-1 is unlocked and drbd is synchronizing. In such cases
the etcd /health check timed out and causes uncontrolled swact.
This change increase the timeout value to 5s.
Test Plan (DX system):
PASS: etcd package build and image build.
PASS: controller-0 successfully installed, bootstrapped and unlocked,
with IPsec enabled.
PASS: controller-1 successfully installed, IPsec configed and enabled,
IPsec SAs established between controllers.
PASS: After controller-1 is unlocked, verify there is no uncontrolled
swact during drbd synchronization, and controller-1 comes up in
"enabled" and "available" state.
