Apostrophe handling in CpsPathParser

Apostrophe is not currently handled correctly, and having apostrophe in
the xpath will lead to various errors.
For example, normalizing this xpath works:
  /path[@name="I'm quoted"] -> /path[@name='I\'m quoted']
However the resulting xpath will throw a PathParsingException if parsed!
(Thus path normalization is not idempotent.)

- Use '' for escaping apostrophe in single quoted leaf value,
  to comply with XPath standard (and use "" for escaping in ").
- Use Liquibase to make existing data comply with new rules.
- Leaf values in data leaves are now unescaped, e.g. "I'm quoted"
- Quoting is now consistent for leaf/text/contains conditions.
