Almost two years ago, we began referring to the project as Fleet, but there are
many occurences of the term "Kolide" throughout the UI and documentation. This
PR attempts to clear up those uses where it is easily achievable.
The term "Kolide" is used throughout the code as well, but modifying this would
be more likely to introduce bugs.
Useful for SAML login users who cannot log in with `fleetctl login`. Instead
they can pull their session token from the UI and configure the fleetctl client
to use it.
Closes#1865
