New releases of oslo.config support a 'mutable' parameter to Opts.
This is only respected when the new method mutate_config_files is
called instead of reload_config_files. Heat delegates making this call
to oslo.service, so how do we switch?
Icec3e664f3fe72614e373b2938e8dee53cf8bc5e allows services to tell
oslo.service they want mutate_config_files to be called by passing a
parameter, which this patch does.
This allows Heat to benefit from
I1e7a69de169cc85f4c09954b2f46ce2da7106d90, where the 'debug' option
(owned by oslo.log) is made mutable. We should be able to turn debug
logging on and off by changing the config and sending SIGHUP.

This patch implements a new heat-all command that can be used
to launch a single process version of the configured heat services.
The end user can control which services are launched by setting
'enabled_services' in the heat config file:
[heat_all]
enabled_services = api,engine
One use case for this launcher would be to launch a single process heat
using rpc_backend = fake, connection=sqlite://heat.db, to have access
to a minimal all in one Heat API/Engine for TripleO undercloud
deployments via Heat templates.

Downstream test environments are frequently having failing stacks with
error messages like:
MessagingTimeout: resources[0]: Timed out waiting for a reply to
message ID ...
These environments generally have 1 or 2 cores, so only spawn one or two
engine workers. This deadlocks with stacks that have many nested stacks
due to engine->engine RPC calls.
Even our own functional tests don't work reliably with less than 4
workers, and the workaround has been to set that explicitly in
pre_test_hook.sh.
This change sets the default minimum number of workers to 4, but still
matches workers to cores for larger servers.
This change also moves the default evaluation to heat.cmd.engine so that
generated configuration doesn't get a inappropriate default value.
