IMPALA-3402: [DOCS] Remove/reword all CDH 4 references Along the way, remove nearby references to CDH 5 and especially the CDH version numbers in the 'Fixed Issues' titles. The fixed issues titles are not amenable to the keydef/keyref substitution technique because they are all 3-part numbers like Impala 2.2.1 that don't have substitution variables defined for them.
