Preclude ensure table exist check which needs create access. fix #619

Create/Admin access is generally available in production scenarios and table creation checks are better avoided.

Most production scenarios would be with a pre-created table with all cfs rightly configured.

[bug 6889954] introduce basic kryo serialization for string. It does utf8 by default. more efficient,also spacewise than the current serialization. Enable turning it on by a configuration variable to allow for default 0.4.x serialization for b/w compat
Fix kryo serialization test cases
add test cases for utf8
Handle zero upper partition bounds

VertexIDAssigner reads the first four bytes of key ranges provided by
getLocalKeyPartition as ints.  It then unsigned right shifts the ints
by two bits each to make them effectively 30 bits wide.  It does some
arithmetic on the ints to preserve inclusive-start and exclusive-end
semantics and then passes them to PartitionIDRange's constructor.

Here's the computation done on each range-end int:

  partition[1] = (partition[1] >>> 2) - 1;

If the original partition[1] value is 0, this results in
Integer.MIN_VALUE.  Because the partition width is 30 bits, this value
is invalid (too wide since the MSB is set).  This value leads to a
precondition failure shortly after in PartitionIDRange's constructor.

I think the intent is to follow the subtraction by zeroing the two
most significant bits, simulating 30-bit wide unsigned integer
arithmetic and allowing underflow.  So this commit adds a bitmask
after subtraction like so:

  partition[1] = (partition[1] >>> 2) - 1;
  partition[1] &= 0x3FFFFFFF;

Optional utf8 serialization
Adjusted the PR to:
1) rename the config option and place it under the attributes namesapce
2) refactor out some code duplication
3) fixed a minor bug in a test case
Use BaseConfiguration instead of PropertiesConfiguration for empty config. Its leaner.
