V1.22 has been released

[n3101]

A small release with the following improvements:

#2562 A bug in GetElementsInSet has been fixed, allowing exclusion by properties.
#2559 Adds a new hasTrait Operation, that replaces a deprecated function.
#2602 Log4J has been replaced by Reload4J, thereby removing a longstanding security vulnerability. Note that the linked Koryphe library still uses Log4J but this is overridden in favour of Reload4J.
#2611 The Hazelcast dependency has been up-versioned to remove the recently reported vulnerability.
#2555 As previously announced, the HBase backing store is now formally deprecated.
#2557 Similarly, the Parquet backing store is also deprecated.
#2540 Conversely the previously deprecated "gafferpy" in Gaffer tools has been un-deprecated; as there is a new idea for it.
