Policy defined for 'share' applies to 'security_service' also

[Aleksandr Chirko]

If we define policy for share creation in the policy.json like that
    "share:create": [["is_admin:True"]]
we will be unable to create share under 'demo' user:
    $manila create nfs 1
    ERROR: Policy doesn't allow share:create to be performed.

 and that's expected.
But we also will be unable to create security service under 'demo' user:
    $manila security-service-create ldap
    ERROR: Policy doesn't allow share:create to be performed.
which is unexpected.

    Fix policy.py

    Because inside check_policy() there is hardcoded
    'share' target prepended to all policies, any
    policy we check will be checked against 'share'
    policy. Change check_policy() to use explicit
    target and action instead of just action.
    Change wrap_check_policy decorator to be a
    decorator maker which accepts resource name
    as an argument.
