Prevent store-contract spamming

[daniel-farina]

I think it would be great if we can prevent beaker from uploading the same contract multiple times on the testnet. For example keep track of hashes/uploader address and if a hash was previously uploaded by the same address then return the existing code instead.

Upload contract:

beaker wasm proposal store-code --proposal prop.yml --signer-account test1 --network testnet counter --gas 25000000uosmo --gas-limit 25000000

Keep track of the artifact/counter.wasm hash & code_id and admin address?

If the users runs the same command again and the hash of the wasm is the same as the one previously uploaded, then return the code_id instead.

This contract was already uploaded. The code_id is: xxxx

This can be added as low priority to the backlog for now.
