OPENDJ-3230-3223: upgrade to 3.5.0 should rebuild indexes using DN
syntax

Allow more flexibility on how to specify the indexes to rebuild.
Rebuild-index is now accepting the format
(attributeType)((.indexType)|(.matchingRuleName)).
This allows to rebuild all indexes for a given attributeType (i.e: "cn")
but also all indexes for a given index type (i.e: ".substring) or
matching rule (i.e: ".caseIgnoreSubstringMatch) and also a combination
of both (i.e: "cn.substring" or "cn.caseIgnoreSubstringsMatch")

Update upgrade tasks so that the rebuild-index performed during upgrades
only reference matchingRules rather than hard-coded attributes.
