add suport for rewritten authwithpubkey in sshhandler

added removefromkeychain
added renamekey
added deletekey
updatekymanagerview to add deleting and ui uodates
remove publickey and passphrase from host
remove key related texboxes in connectionview
added a passwordstore instance
made keytypes and names published
added savekeypairs
updatedsavetokeychain to remove and readd if it exists in the keychain
update getkeys
remove authwithbiometrics from hostmanager
trying to add key renaming support
remove Key (unused)
cleanup
