Is this a board farm for manually allocating devices or is this a pool for
continuous integration testing with devices being allocated automatically
as jobs are generated from commits?

LAVA is aimed at the CI device pool. Depending on the number of devices
available and the expected number of jobs, you can have some devices
available to particular teams and run the CI on others, it just requires a
little bit of planning.

LAVA has internal device management (using Jinja2 templating).

The two systems manage devices in different ways according to the different
use cases.

LAVA supports any power control scripting that the admins can administer
reliably. The Linaro lab in Cambridge uses SNMP for PDU control.
