Output more helpful error messages for pipeline runtime errors

[mfelsche]

Pull request

Description

If we have an error that is locatable within the pipeline source, we are going do display an error message, showing the error within the pipeline source.

Also:

• Added integration tests for hygienic runtime error messages
• Added possibility to add environment variables in command based tests (turns out it wasnt needed)
• Put error messages to stderr when using tremor run.

Related

• Related Issues:
• fixes Non hygenic error with bad access in trickle #588
• fixes minimal value of i64 can not be expressed in tremor script #127

Checklist

• The RFC, if required, has been submitted and approved
• Any user-facing impact of the changes is reflected in docs.tremor.rs
• The code is tested
• Use of unsafe code is reasoned about in a comment
• Update CHANGELOG.md appropriately, recording any changes, bug fixes or other observable changes in behavior
