initial code repo

This patch creates initial code repo.

For ceph, luminous stable release will be used for base code,
and next changes and optimization for ceph will be added to it.

For opensds, currently any changes can be upstreamed into original
opensds repo (https://github.com/opensds/opensds), and so stor4nfv
will directly clone opensds code to deploy stor4nfv environment.
And the scripts for deployment based on ceph and opensds will be
put into 'ci' directory.

+===============
+Bucket Policies
+===============
+
+.. versionadded:: Luminous
+
+The Ceph Object Gateway supports a subset of the Amazon S3 policy
+language applied to buckets.
+
+
+Creation and Removal
+====================
+
+Bucket policies are managed through standard S3 operations rather than
+radosgw-admin.
+
+For example, one may use s3cmd to set or delete a policy thus::
+
+  $ cat > examplepol
+  {
+    "Version": "2012-10-17",
+    "Statement": [{
+      "Effect": "Allow",
+      "Principal": {"AWS": ["arn:aws:iam::usfolks:user/fred"]},
+      "Action": "s3PutObjectAcl",
+      "Resource": [
+        "arn:aws:s3:::happybucket/*"
+      ]
+    }]
+  }
+
+  $ s3cmd setpolicy examplepol s3://happybucket
+  $ s3cmd delpolicy s3://happybucket
+
+
+Limitations
+===========
+
+Currently, we support only the following actions:
+
+- s3:AbortMultipartUpload
+- s3:CreateBucket
+- s3:DeleteBucketPolicy
+- s3:DeleteBucket
+- s3:DeleteBucketWebsite
+- s3:DeleteObject
+- s3:DeleteObjectVersion
+- s3:DeleteReplicationConfiguration
+- s3:GetAccelerateConfiguration
+- s3:GetBucketAcl
+- s3:GetBucketCORS
+- s3:GetBucketLocation
+- s3:GetBucketLogging
+- s3:GetBucketNotification
+- s3:GetBucketPolicy
+- s3:GetBucketRequestPayment
+- s3:GetBucketTagging
+- s3:GetBucketVersioning
+- s3:GetBucketWebsite
+- s3:GetLifecycleConfiguration
+- s3:GetObjectAcl
+- s3:GetObject
+- s3:GetObjectTorrent
+- s3:GetObjectVersionAcl
+- s3:GetObjectVersion
+- s3:GetObjectVersionTorrent
+- s3:GetReplicationConfiguration
+- s3:ListAllMyBuckets
+- s3:ListBucketMultiPartUploads
+- s3:ListBucket
+- s3:ListBucketVersions
+- s3:ListMultipartUploadParts
+- s3:PutAccelerateConfiguration
+- s3:PutBucketAcl
+- s3:PutBucketCORS
+- s3:PutBucketLogging
+- s3:PutBucketNotification
+- s3:PutBucketPolicy
+- s3:PutBucketRequestPayment
+- s3:PutBucketTagging
+- s3:PutBucketVersioning
+- s3:PutBucketWebsite
+- s3:PutLifecycleConfiguration
+- s3:PutObjectAcl
+- s3:PutObject
+- s3:PutObjectVersionAcl
+- s3:PutReplicationConfiguration
+- s3:RestoreObject
+
+We do not yet support setting policies on users, groups, or roles.
+
+We use the RGW ‘tenant’ identifier in place of the Amazon twelve-digit
+account ID. In the future we may allow you to assign an account ID to
+a tenant, but for now if you want to use policies between AWS S3 and
+RGW S3 you will have to use the Amazon account ID as the tenant ID when
+creating users.
+
+Under AWS, all tenants share a single namespace. RGW gives every
+tenant its own namespace of buckets. There may be an option to enable
+an AWS-like 'flat' bucket namespace in future versions. At present, to
+access a bucket belonging to another tenant, address it as
+"tenant:bucket" in the S3 request.
+
+In AWS, a bucket policy can grant access to another account, and that
+account owner can then grant access to individual users with user
+permissions. Since we do not yet support user, role, and group
+permissions, account owners will currently need to grant access
+directly to individual users, and granting an entire account access to
+a bucket grants access to all users in that account.
+
+Bucket policies do not yet support string interpolation.
+
+Currently, the only condition keys we support are:
+- aws:CurrentTime
+- aws:EpochTime
+- aws:PrincipalType
+- aws:Referer
+- aws:SecureTransport
+- aws:SourceIp
+- aws:UserAgent
+- aws:username
+
+More may be supported soon as we integrate with the recently rewritten
+Authentication/Authorization subsystem.
+
+Swift
+=====
+
+There is no way to set bucket policies under Swift, but bucket
+policies that have been set govern Swift as well as S3 operations.
+
+Swift credentials are matched against Principals specified in a policy
+in a way specific to whatever backend is being used.
