remove info about Juju HA from Charm HA page and make a new page for Juju HA.
URL tweaking to reference exact relation hooks. Dropped some notes regarding bugs that have been resolved for some time. Note in authors-charm-hooks was broken, syntax changed to reflect Juju markdown syntax. Changed authors-charm-hooks references to hooks, such as -joined, to make it more obvious / stand out more against the paragraphs and walls of text. Dropped hook-kinds since it was just an outdated version of charm-hooks.
