docs:Missing sudo command

[ismailkayi]

Please describe the question or issue you're facing with "Mount MicroCeph backed Block Devices - MicroCeph documentation".

There must be a sudo in the last command (sudo rbd pool init block_pool), otherwise, it will give an error as "rbd: couldn't connect to the cluster!".

Create a pool for RBD images:

$ sudo ceph osd pool create block_pool pool 'block_pool' created

$ sudo ceph osd lspools 1 .mgr 2 block_pool

$ rbd pool init block_pool

There must be a sudo in the last command.
