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.

ASTERIXDB-1302 ASTERIXDB-1301 Fix Socket Feed Connection

A bug causes a read lock to never be released when a feed is

connected with "wait-for-completion" set to false. The bug

was fixed and a test case was added.

Another bug was causing the socket feed to not receive

connections correctly. The bug was fixed and a test case

was added.

Additionally, this change ensures that adapters have absolute

partitions to ensure consistency with regards to feed log

manager.

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.

Add flush() to IFrameWriter

This method is expected to be used with feeds to push

frames all the way to storage when needed. As of now, it is

needed in two cases:

1. No activities in ingestion node and need to push content

so it can be stored.

2. When the ingestion node needs to move the checkpoint ahead

if the at least once semantics are used.

Two feeds make use of this function. The filesystem feed and

couchbase feed which was introduced as well in this change.
