ASTERIXDB-1360 Fix Error Message for Unknown Format

This change includes some refactoring for external

data. This refactoring makes the code less error prone

and separate data source selection from data parser

selection. It also fixes issue ASTERIXDB-1366 and adds

a test case for it as well.

Improve Error Handling in Local Directory Feeds

This change improves handling of two error types for filesystem

based feeds. The first one is the handling of IO Errors which

causes the input stream to be closed, and the second one is

reacting to missed filesystem events. In both cases, we scan the

directory and compare it with the history we have in order to

resume from where we last left off.

In addition, this change includes some refactoring in external

data. Particularly, we get rid of the stream provider layer and

instead, stream factories create input streams directly. This

is consistent with record reader factories which create readers

directly without reader providers.

Support Change Feeds and Ingestion of Records with MetaData

This change allows feeds to perform upserts and deletes

in order to perform replication of an external data source.

The change does so by performing the following:

1. The adapter produces [PK][Record]. (Record == null --> delete)

2. The insert is replaced by an upsert operator.

Enabled Feed Tests and Added External Library tests

Feed tests had been switched off for a while due to having too many

sporadic failures. Now, we are switching them back on.

In addition, a new set of tests have been added to test that external

library works as expected.
