[pve-devel] [PATCH manager v3 1/4] show optional consent-banner before login

[Gabriel Goller <g.goller@proxmox.com>]

Add ConsentBanner variable to html template and populate it from the
`datacenter.cfg` config file. Add Datacenter option to set the text and
trigger the popup on login. The max length of the input is 63*1024,
which is a bit less than the max body size for a api request (64*1024).
