Can we have an option to import clients when hydra's starting? Something like:

hydra host --import clients.json

and clients.json:

[
{ client_1},
{ client_2}
]

There's hydra clients import client.json, but it needs client's credentials and I don't want to paste this every time from command line.

Use case:

• On hydra's startup I need to add couple of predefined clients for IDPs and have hydra add them to the database.
• On next startup hydra should ensure that all clients from the list are present, possibly update the configuration.
