Base implementation of FilePullerDeviceMetricCollector that allows pulling the perfetto files from the device and collect the metrics from it.

Summary

Public constructors
`PerfettoPullerMetricCollector()`

Public methods
`void`	`processMetricDirectory(String key, File metricDirectory, DeviceMetricData runData)` Implementation of the method should allow to log the directory, parse it for metrics to be put in `DeviceMetricData`.
`void`	`processMetricFile(String key, File metricFile, DeviceMetricData data)` Process the perfetto trace file for the additional metrics and add it to final metrics.

Protected methods
`CommandResult`	`runHostCommand(String[] commandArgs)` Run a host command with the given array of command args.

public void processMetricDirectory (String key, 
                File metricDirectory, 
                DeviceMetricData runData)

Implementation of the method should allow to log the directory, parse it for metrics to be put in DeviceMetricData.

Parameters
`key`	`String`: the option key associated to the directory that was pulled.
`metricDirectory`	`File`: the `ERROR(/File)` pulled from the device matching the option key.
`runData`	`DeviceMetricData`: the `DeviceMetricData` where metrics can be stored.

public void processMetricFile (String key, 
                File metricFile, 
                DeviceMetricData data)

Process the perfetto trace file for the additional metrics and add it to final metrics.

Parameters
`key`	`String`: the option key associated to the file that was pulled from the device.
`metricFile`	`File`: the `ERROR(/File)` pulled from the device matching the option key.
`data`	`DeviceMetricData`: where metrics will be stored.

protected CommandResult runHostCommand (String[] commandArgs)

Run a host command with the given array of command args.

Parameters
`commandArgs`	`String`: args to be used to construct the host command.

Returns
`CommandResult`	return the command results.
