describe output of `gravity eth_keys add`

[adamb]

In the docs in this section it says to run gravity eth_keys add but doesn't describe why or the output.

An example would be helpful:

# create the Gravity Orchestrator Cosmos Key (private: in the command output
$ gravity eth_keys add

private: 0xce124acdcca17a5715aa61dfe64f5146a4a519b451134a759fe5124e89724fe3
public: 0x04f682c57545836570421227040c782fca11c546e518bc21720ade3d09c6fc3d9e8f0cd300a22189ac1737ded8dda8cdf55e5c477de9f6c131810e895837f3d522
address: 0xBb6a1d1a3737bD8d5c35224070EC22f22D861960

Are any of these the keys we need later? Is one of them the Gravity Orchestrator Cosmos Key Name that is needed in the next step? I think it's maybe the private key.

Are any of these keys important to keep private? Can someone steal my funds if they know them?

Also this command seems to create files in ~/.gravity but that's not mentioned in the documentation or the gravity eth_keys add --help
