Recursive listing and copying between Vault clusters

• Ported functionality of vaultcp.sh and vaultls.sh to golang - Faster!
• Live copy from source Vault to dest Vault (no code generation step in the middle)
• Recursive list of a source Vault produces an output file containg the path to each secret and its data value
• Support pre and post Vault v0.10 style kv api

Copy secrets between vault clusters

• A Vault secret migration code generator script.
• A source Vault is recursively listed and read and for each secret a write command will be generated to a worker script.
• A master script vaultcp.out will execute in parallel the worker scripts vaultcp.out.0 .. vaultcp.out.9
• The source vault is specified by VAULT_ADDR and an admnin token with VAULT_TOKEN env variables.
• The generated master script should have the destination Vault and token defined by different values for these env variables.

Recursively list secrets under secret/
