Discuss home logic

[labkode]

To simplify our lives:

1. We need to include Separation of concerns: storage providers should not know about their mount path #578, that will mean that the SP responsibility is to always handle paths that start with root (/), only for forever, mount paths are left to the gw+registry.

2. Assuming 1, we can configure a SP to be provider of a home. That means that this SP will need to map root(/) to a user home directory. Internal business is not exposed.

Having 1 and 2, we can enforce namespace in the gateway the following convention:

• /home to always map to the home SP (this means GetHome() on the GW always returns /home)

Still leaving the possibility to expose the home SP under other paths:

• /users/ can also be mapped to the home SP (this means GetHome() on the GW needs to take into consideration the user in context and reply with /users/hugo and use it for wrap/unwrap paths instead of just home. This model is particularly useful when exposing the home directory of a user in a global view.

With these changes there is not need anymore of having the GetHome method implemented in the SP and in the storage drivers, simplifying its implementation.
