[Pki-devel] [PATCH] 426 Added search filter for TPS resources.

The TPS resources have been modified to accept a basic search filter for find operation. For resources based on LDAP database, the filtering is done using LDAP filter. For other resources, the filtering is done using string comparison. For now the filter is will only be matched against entry IDs. In the future the filter may be expanded to support other entry attributes. The CLI has been updated accordingly. The total attribute in DataCollection was changed from Integer into int because the total size of the collection cannot be null. The PKIException constructors have been consolidated into a single actual constructor. The other constructors have been modified to call the actual constructor with some default values.
