Allow specifying FuzzyRowFilter for Table's scan

Description

We need it for the work around extracting Cube dataset out of Metrics System code. The Cube implementation uses the FuzzyRowFilter to efficiently scan across time series aggregations.

For now, to avoid big changes in Table API and keep iterative approach, it is suggested to add Scan with minimal Filter parameter. There will be no Filter implementations available for developers (in cdap-api), while datasets that come with cdap will be able to use FuzzyRwFilter from internal code.

Later, we'll use this first step to help polish the server-side fitlers APIs for Table

we have implementations for leveldb and inmem - this jira is about using what we have in metrics code already. For now, not exposed to user

How is that gonna work in standalone, where we don't have HBase but LevelDB? We can't apply an HBase filter there.
