Use diffrent kras configurations

[LBraeschke]

New Feature Proposal

Provide a command line argument to bootstrap different .krasrc files.

Description

The kras library already provides the possibility to provide the config file via a command line argument. May the same could be implemented for the prial debug command:
for example:
piral debug -- config=local.krasrc

Background

By default the piral debug command will use a .krasrc file which can be provided in the same folder. In our project we use the proxy for local development as well as the emulator.

For local development we would like to use a different configuration file, to do reduce the risk to create a misconfigured emulator by accident.
