trim whitespace from values in schema tool property files

[punktilious]

The schema tool uses values from properties files to configure the database connection. Trailing spaces may not be obvious and can cause issues if they are used in SQL statements (typically when used with bind variables).

The schema tool should trim values and ideally warn when the trim changes the value.

Additionally, the values must be checked with DataDefinitionUtil#assertValidName(String name).
