Describe the bug
Following the tern guide on its homepage, 'tern report' command fails with the warning of Cannot retrieve full image metadata. This happens right after fs_hash.sh script is called.

To Reproduce
Steps to reproduce the behavior:

  1. Use the vagrant file provided by tern to create a VM in vagrant.
  2. Use steps to setup all tern requirements on the VM and setup tern repository
  3. Run command tern -l report -f output.txt -i hello-world
  4. 2019-04-09 02:54:55,847 - WARNING - report - Cannot retrieve full image metadata

Error in terminal

Adding 'attr' install in vagrant bootstrap.
4f420cd 
fs_hash.sh uses getfattr to collect detailed file attributes. This
functionality is not available on native ubuntu so bootstrap has to
take care of installing it on the VM.

As 'attr' library was not available on the VM, the dependency to run
'tern report' was missing. That resulted in failure to generate report
with 'Cannot retrieve full image metadata'. fs_hash.sh collects detailed
file attributes using 'attr' library. As this dependency was not met,
the command used to return error.

Resolves: tern-tools#220
