This makes sure the library version works with the server version.

Ideally we'd also want to check the version so we can error out if a too
old keycloak server is on the other side, but I don't see any public API changes
that would allow us to know if the library is too old.

Activate Matomo logging only after user logged in successfully. Deactivate if user logs out.

Using lerna with npm breaks various npm commands such as "outodated"
etc.

Switch yarn with namespaces. lerna is only used to run commands on all
packages and maybe publish them etc. yarn 2.x has extra workspace features
like running commands for all packages, so with 2.0 we might also get
rid of lerna.
