regulators: Implement D-Bus configure method

The phosphor-regulators D-Bus configure method is called from a service
file when booting the BMC system. The method is called shortly before
the regulators are enabled (turned on).

Previously the configure method did not do anything; it was a
placeholder.

This commit adds the implementation of the configure method. The method
now configures the regulator devices in the system using the rules and
actions in the JSON config file.

Also commented out the partial implementation of the D-Bus monitor
method. This method has not been fully implemented or tested yet.

Tested:
* Tested phosphor-regulators application through chassison/chassisoff
and poweron/poweroff.
* Verified systemd state and journal messages.
* Verified that all configuration specified in the config file was
applied to the regulators.
* Tested when an I2C failure occurs when configuring a regulator.
* Verified that monitoring can be safely enabled and disabled but it
performs no current function.

regulators: Load JSON config file

There are three basic steps to loading the JSON configuration file
for the phosphor-regulators application:
* Find the correct base name using a D-Bus query
* Find the absolute path to the file by searching two directories
* Parse the config file and store the resulting C++ objects

The base name is currently hard-coded while waiting for an EntityManager
enhancement to be completed. So the first step is partially done.

This commit implements the second and third steps.

Some minor changes were also made to conform these files to the coding
conventions used in the rest of the phosphor-regulators application.

Tested:
* See test plan:

regulators: Temporarily hard-code config file name

The JSON configuration file name for the current system will be obtained
from a D-Bus interface and property. That interface will be provided by
the EntityManager application.

Unfortunately the interface is not yet completely defined or
implemented. While waiting for this interface to be completed, a
hard-coded JSON config file name will be used. This is expected to be a
very short-term solution (a few weeks).

Add 'long-tests' build option

Add a new meson build option for handling long-running tests that should
be excluded from CI.

Meson enforces a timeout on testcases. If the testcase runs longer than
the timeout value, the testcase is considered failed.

The timeout value can be increased, but sometimes this is still
insufficient. Testcases are run multiple times in CI, including within
environments like valgrind that increase their run times.

Very long running testcases should probably be excluded from CI runs
rather than setting the timeout to an arbitrarily large value like 5
minutes.

The 'long-tests' option defaults to disabled. Long-running tests will
only be built and run if option is explicitly set to enabled.
