[pve-devel] [PATCH manager v2] add HostList validator and check monhosts with it

[Dominik Csapak]

this adds a vtype which splits the given string into a list by
; or , or space
and checks if only valid characters are in it
the real check has to be done on the host,
since the client check is run on every keystroke

also make the rbd monhost input field use it

i did not want to introduce a huge regex check for every
host here, as it gets executed with every keystroke

on the backend this check has to be done only once and
with a click on "OK" you should get the error from the backend
anyway
