[SP-1612] - Regression of PDI-13082 - Regression: MapReduce Input is missing Serializable Data Type (5.2 Suite)

the Serializable datatype in this drop-down list was lost on making ValueMeta pluggable (4->5)
using ValueMeta.getAllTypes() instead of ValueMeta.getTypes() resolves the issue.
However, even after fix the HBase Row Decoder step does not produce the correct output.
There are two possible options:
1. The bug in either PentahoTableInputFormat or in HBaseRowDecoder classes
2. Wrong configuration of the Hadoop/DPI

In both cases this looks like a separate issue which has to be reported in Jira separately.
Merge pull request #274 from mtseu/sp-1612
