Start all(or multiple) scans of a project at once

[sbalka]

When multiple scan tools are used for a single project, starting all scans one by one might be inefficient. Also in DevOps pipelines, writing another line and controlling each one separately is not the best way.

There might be a flag for scan command like --all to start all scans of the project at once. Alternatively, user could be able to add several tools with tool flag instead of just one. Open for discussion @ckalpakoglu @cbilgin23 @yeyisan
