Introduced patternfly empty state for Baremetal inventory

[betherly]

Implemented HostsEmptyState component for Baremetal inventory.
WIP due to need assistance with aligning the EmptyState component
to centre. Styling margin: 0 auto; works, so need to identify
a patternfly component or class that implements that styling.

We are using https://prettier.io/ for code formatting. You can apply it either by running yarn prettier or add it to your editor for automatic formatting on save. Doing this will fix most of the linting errors.

You can use <Bullseye> component to align the HostsEmptyState to the center (https://patternfly-react.surge.sh/patternfly-4/layouts/bullseye) See #27. Don't worry about the scrollbar, I am fixing it in #27

Looks good! Please fix the linting warnings.

If you rebase your branch on top of master, you'll get a proper build failure here.

Might be worth documenting the prettier stuff in the README, @jtomasek

Looks good, there is one wrong import (comment inline)
