This will be useful for other commands that might want to interact
with the network to perform tasks related to DA. One example is
the upcoming testnet demo.
* Send DA certificate to node after dissemination
* rename mempool endpoints
* Check certificate inclusion in tests
* rename endpoint
* Rename addcert and addtx to add
* tweak test condition
* add option to save certificate to file
* move thread join
* remove fancy prints
* Add nomos-cli command to disseminate data across the network
Add nomos-cli to hold various utilities for the node.
To start, this commit adds a command to disseminate some
data through the network and build a certificate of correct
dispersal for inclusion in a block
* fmt
* reorder loop instructions
* Send blobs concurrently
