eren 793cb2d004 ADD master_modify_multiple_shards UDF 
Fixes #10

This change creates a new UDF: master_modify_multiple_shards
Parameters:
  modify_query: A simple DELETE or UPDATE query as a string.

The UDF is similar to the existing master_apply_delete_command UDF.
Basically, given the modify query, it prunes the shard list, re-constructs
the query for each shard and sends the query to the placements.

Depending on the value of citus.multi_shard_commit_protocol, the commit
can be done in one-phase or two-phase manner.

Limitations:
* It cannot be called inside a transaction block
* It only be called with simple operator expressions (like Single Shard Modify)

Sample Usage:
```
SELECT master_modify_multiple_shards(
  'DELETE FROM customer_delete_protocol WHERE c_custkey > 500 AND c_custkey < 500');
```
