Update OSCAR info panel

[IgnacioHeredia]

This is the current state:

We should group the parameters endpoint and token onto a group called: Synchronous calls.

The we need to create an additional group called Asynchronous calls and there create the following parameters:

• MINIO bucket: this is service['name']
• MINIO URL: this is service['storage_providers']['minio']['default']['endpoint']
• MINIO access key: this is service['owner']
• MINIO secret key: this is service['storage_providers']['minio']['default']['secret_key']

MINIO access key: this is service['owner']

@MartaOB I have updated PAPI so that this info can be retrieved from service['storage_providers']['minio']['default']['access_key']. It's better to adapt to this because the access key might not always end up being the EGI token.
