Managing Crush map buckets with Ceph Rest API

Possibilities for managing buckets are:

• add-bucket
• link
• move
• rm or remove

The URL syntax is :

/api/v0.1/link?name=bucketname&args=buckettype=bucketname [args=buckettype=bucketname]

exemple:

R1- /api/v0.1/add-bucket?name=myhost&type=host

R2- /api/v0.1/link?name=myhost&args=datacenter=houston&args=root=default

R1 will create 'myhost' of type 'host' but with no link
R2 will create or establish a tree for 'myhost' in crushmap

root -> datacenter ->host
default -> Houston -> myhost
