Enforce Password Complexity Requirement

Some administrators would like to be able to enforce a password complexity requirement for the default realm.

Acceptance

• A property exists which enables an an administrator to specify a password complexity policy
• Administrators can use regexp (or the like) to configure their password complexity requirement somewhere in sonatype-work
  • This is a regular expression for the policy
  • plus a textual description of the policy (e.g. "At least one French accented character")
  • (for now no UI is necessary to update this policy)
• All methods of updating/creating passwords for the default realm are checked for compliance with this policy
