Request to support for custom hd-home location

[JohnNiang]

Developers want to add a new configuration into hd-home, in addition to moving configuration file into a specific location, it will be very difficult to test against it.

Currently steps to test:

1. Create configuration file: project.yaml
2. Move the configuration file into ~/.config/hd-home/config/repo/project.yaml
3. Execute command hd to test: hd get --fetch=false repo/project

Expect steps to test:

hd get --config-location=~/workspaces/hd-home repo/project

If we specific config-location flag, then the fetch flag will be ignored.
