html escape service checks

[davidnewhall]

• Closes #760

Turns out we already limit the output 150 characters.

To the body output:

• Added html escaping.
• Replaced white space strings (spaces, tabs, newlines) with single spaces.
• Truncate output string after redacting secrets.
• Apply max length check to entire output string and not just body.
• Increase max from 150 to 170 to account for the change in view.
