Introduce save-overrides.toml

[orchestr7]

This file should contain following options:

• execCmd (or initially overrideExecCmd)
• execFlags (before Merge execCmd and execFlags options: provide a common template #434, later can be skipped)
• batchSeparator
• batchSize

As bonus - should be done separately later:

This file should support groups [fix]and[warn] to customize execution run for different type of plugins

It allows to store such files in private repositories for test and provide them as external file for public tests.

Try to move evaluatedToolConfig to Plugin's field level

Better to handle it in scope of #434
