NIFI-2909 Adding per-instance class loading capability through @RequiresInstanceClassLoading annotation 

NIFI-1712 Applying per-instance class loading to HBaseClientService to allow specifying Phoenix Client JAR

-Refactoring the ClassLoading so that every processor, controller service, and reporting task gets an InstanceClassLoader with a parent of the NAR ClassLoader, and only components with @RequiresInstanceClassLoading will make a copy of the NAR ClassLoader resources, and addressing some review feedback

This closes #1156

[[per-instance-classloading]]
== Per-Instance ClassLoading
A component developer may wish to add additional resources to the component’s classpath at runtime.
For example, you may want to provide the location of a JDBC driver to a processor that interacts with a
relational database, thus allowing the processor to work with any driver rather than trying to bundle a
driver into the NAR.
This may be accomplished by declaring one or more PropertyDescriptor instances with
`dynamicallyModifiesClasspath` set to true. For example:
[source,java]
----
PropertyDescriptor EXTRA_RESOURCE = new PropertyDescriptor.Builder()
.name("Extra Resources")
.description("The path to one or more resources to add to the classpath.")
.addValidator(StandardValidators.NON_EMPTY_VALIDATOR)
.expressionLanguageSupported(true)
.dynamicallyModifiesClasspath(true)
.build();
----
When these properties are set on a component, the framework identifies all properties where
`dynamicallyModifiesClasspath` is set to true. For each of these properties, the framework
attempts to resolve filesystem resources from the value of the property. The value may be a
comma-separated list of one or more directories or files, where any paths that do not exist are
skipped. If the resource represents a directory, the directory is listed, and all of the files
in that directory are added to the classpath individually.
Each property may impose further restrictions on the format of the value through the validators.
For example, using StandardValidators.FILE_EXISTS_VALIDATOR restricts the property to accepting a
single file. Using StandardValidators.NON_EMPTY_VALIDATOR allows any combination of comma-separated
files or directories.
Resources are added to the instance ClassLoader by adding them to an inner ClassLoader that is always
checked first. Anytime the value of these properties change, the inner ClassLoader is closed and
re-created with the new resources.
NiFi provides the `@RequiresInstanceClassLoading` annotation to further expand and isolate the libraries
available on a component’s classpath. You can annotate a component with `@RequiresInstanceClassLoading`
to indicate that the instance ClassLoader for the component requires a copy of all the resources in the
component's NAR ClassLoader. When `@RequiresInstanceClassLoading` is not present, the
instance ClassLoader simply has it's parent ClassLoader set to the NAR ClassLoader, rather than
copying resources.
Because @RequiresInstanceClassLoading copies resources from the NAR ClassLoader for each instance of the
component, use this capability judiciously. If ten instances of one component are created, all classes
from the component's NAR ClassLoader are loaded into memory ten times. This could eventually increase the
memory footprint significantly when enough instances of the component are created.
