(#14670) autorequire a file_line resource's path

If we manage a file we edit with file_line, it should be autorequired by
file_line.  Without this patch applied the relationship is not
automatically setup and the user is forced to manually manage the
relationship.
(#14670) Fixup file_line autorequire specs

Without this patch applied the file_line autorequire examples are
failing.  This is a problem because the failures are false positives and
should be passing given the implementation.

This patch fixes the problem by changing the examples to directly test
the existence of the relationship by finding it in the list of
autorequire relationships.

Add an ensure_packages function.

Its often the case that modules need to install a handful of packages.
In some cases its worth breaking these dependencies out into their own
modules (e.g., Java). In others it makes more sense to keep them in the
module. This can be problematic when multiple modules depend on common
packages (git, python ruby, etc). ensure_resource was a good first step
towards solving this problem. ensure_resource does not handle arrays and
for 3 or more packages stamping out ensure_resource declarations is
tedious.

ensure_packages is a convenience function that takes an array of packages
and wraps calls to ensure_resource. Currently users cannot specify
package versions. But the function could be extended to use a hash if
that functionality would be useful.
Add example behaviors for ensure_packages() function

Without this patch the ensure_packages() function has no rspec behavior
examples.  This patch fixes the problem by filling out a spec file with
expected behaviors I could think of.
(Maint) Add spec/functions to rake test task

Without this patch the `test` rake task does not exercise the
rspec-puppet behaviors located in spec/functions/  This is a
self-evident problem.

This patch fixes the problem by adding spec/functions to the list of
directories scanned for spec tests.

Revert "(Maint) Add spec/functions to rake test task"

This reverts commit dbe3c8ecf6379963f583ea11e51e403e5ad55002.

Because testing these against Puppet 2.6.x is causing failures.  These
need to be cleaned up, but I want to leave and this was the behavior
before I tried to "fix" it.
