   ## What changes were proposed in this pull request?
   
   Currently, AllocateBlock takes two major arguments: size and num. There are 
some problems in the current API:
   
   1. For EC replication type, the allocated size for clients to write is 
`size` * `ec.numData` * `num`, which is not a good abstraction from the HDDS 
client's view.
   2. It assumes all blocks are in same size. However, sometimes it's useful to 
let SCM allocate arbitrary size the client wants (e.g. when client know the key 
size in advance).
   
   In this Jira, I wish to add a `requestedSize` field in the AllocateBlock RPC.
   SCM will calculate how many blocks to allocate based on `requestedSize`,
   and return size of each block allocated to client.
