Fuel plugin builder generates spec which creates a symlink, which breaks backward compatibility

[Evgeniy L]

Detailed bug description:
 Fix https://github.com/openstack/fuel-plugins/commit/3f33bf09e3df3a66a01d6a7bb4d324a62975c700
 https://bugs.launchpad.net/fuel/+bug/1603987
 leads to rpm installation errors, if it was previously workarounded manually.

Transaction check error:
  file /var/www/nailgun/plugins/connectivity_checker-9.1 conflicts between attempted installs of connectivity_checker-9.1-9.1.2-1.noarch and connectivity_checker-9.1-9.1.2-1.noarch

Moreover the fix is broken, because `deployment_scripts` must not be hardcoded in the spec, because it is not static, but dynamic parameter which is configured in metadata.yaml

Workaround:
 Use older version of fuel-plugin-builder
Impact:
 Impacts all users whose plugins are built with newest fpb and those users who used workaround by creating symlink manually. And all plugins where deployment_scripts is configured to different one.

Description of the environment:
 fpb 4.1.0

    Create symlink which is required for master node plugin tasks

    Place where plugins are linked depends on configuration (of Nailgun,
    MCollective, Astute), hence must not be hardcoded in specs and
    should be done by puppet manifests which own master node configuration
    details.
