Use dot notation rather than camel case for profile props (SPR-7508)

Before this change, the following properties could be used to manipulate
Spring profile behavior:

    -DspringProfiles=p1,p2
    -DdefaultSpringProfile=pD

These properties have been renamed to follow usual Java conventions for
property naming:

    -Dspring.profile.active=p1,p2
    -Dspring.profile.default=pD
