toggle permission to `upload`,`delete`, `update`, `move`, `copy` and `rename`.

[Sriep]

There is a new toggle to allow upload,delete, update, move, copy and rename.

Boolean fields controlling this will be added to the allocation object blobber gets from 0cahin. Each of upload,delete, update, move, copy and rename should only be permitted if the corresponding field in the allocation object permits it.

This change is blocked by https://github.com/0chain/0chain/issues/828.

@Sriep Can you please explain this a bit more with some appropriate links?

Requires https://github.com/0chain/0chain/pull/1553 to be merged.

We should send the transaction type, upload, delete, update, move, copy or rename to 0chain when committing the transaction. So we need to add this to the write marker.

We just need 3 different states. a) default - as in mutable - all crud operations are allowed b) upload-only, so no updates, rename, copy, move, delete c) immutable - no cruds are allowed except for reads @Sriep @lpoli @cnlangzi
