There are 2 test failures.
- CASSANDRA-17291: testTokenGenerator_single_rack_or_single_rf
- test_cql_reserved_keywords
I reverted the change to the "reserved_keywords.txt" file and started a new
run:

Apparently, the function name 'maxwritetime' has to be added to the unreserved
keywords.
The latest run looks green

> Add new CQL function maxWritetime

> The function "writetime" does not support multi-cell types, e.g. collections
> and UDT. It would be useful to enable querying the latest modified timestamp
> of a column value.
> I'd like to propose to add a new function named "maxWritetime", which returns
> the largest timestamp amongst the cells. When being applied to the single
> cell types, it returns the same result as "writetime".
