Consider upgrading heritrix 1.x dependency from 1.14.1 (adjusted) to 1.14.4

[kurtlenfesty]

The current heritrix dependency for harvest-agent-h1, as per its pom.xml:

		<dependency>
			<groupId>org.archive</groupId>
			<artifactId>aheritrix</artifactId>
			<version>1.14.1</version>
			<scope>compile</scope>
		</dependency>

but once the replace-jboss-soap-with-latest-jaxws-rt is merged into the master branch, that dependency will change to:

		<dependency>
			<groupId>org.archive</groupId>
			<artifactId>heritrix</artifactId>
			<version>1.14.2-webcuratortool-2.0.1</version>
			<scope>compile</scope>
		</dependency>

This version of heritrix is based on the 1.14.1 version source code downloaded from sourceforge, specifically:
https://sourceforge.net/projects/archive-crawler/files/archive-crawler%20%28heritrix%201.x%29/1.14.1/

and then packaged into a source code repository with bug fixes and dependency changes:
https://github.com/WebCuratorTool/heritrix-1-14-adjust

which also requires an updated commons-httpclient and commons-pool:
https://github.com/WebCuratorTool/commons-httpclient-heritrix-1-14
https://github.com/WebCuratorTool/commons-pool-heritrix-1-14

There is a more recent version of heritrix available on sourceforge, 1.14.4:
https://sourceforge.net/projects/archive-crawler/files/archive-crawler%20%28heritrix%201.x%29/1.14.4/

We will assume that this version contains some bug fixes and optimisations, which can be discovered through a code compare of the sources. There are about 120 source files that have changed between heritrix 1.14.1 and heritrix 1.14.4.

We may decide that we want to upgrade the Heritrix 1 version to include the changes up to 1.14.4, which would involve merging the changes in the 1.14.4 source with the changes made in the https://github.com/WebCuratorTool/heritrix-1-14-adjust code repository.

This may become a moot point if the Web Curator Tool drops support for Heritrix 1.x.
