[pbs-devel] [PATCH proxmox-backup v3] restrict consent-banner text length

[Gabriel Goller]

Add a maxLength in of 63*1024 in the frontend. We allow a max body
size of 64*1204 in the api and to allow some other properties to
coexist, reserve 1024 characters. In the backend we set the limit to
128000 (128kB), which is the same as in pve.

v3:
 - forgot to update the actual number in code

v2, thanks @Thomas:
 - limit consent-text in the backend as well
 - set the limit according to the max body size
