Description

Currently, TimestampBasedKeyGenerator only supports 4 data types for the partition key. They are  Double, Long, Float and String. However, if the `avro.java.string` is not specified in the schema provided, Hudi throws the following error:

org.apache.hudi.exception.HoodieNotSupportedException: Unexpected type for partition field: org.apache.avro.util.Utf8
at org.apache.hudi.utilities.keygen.TimestampBasedKeyGenerator.getKey(TimestampBasedKeyGenerator.java:111)
at org.apache.hudi.utilities.deltastreamer.DeltaSync.lambda$readFromSource$f92c188c$1(DeltaSync.java:338)
....

It will be better if the support was more generalised to include the data types that provide method to convert them to String such as `Utf8` since all these methods implement the `CharSequence` interface.
