Use GB (Gigabytes) instead of Go (Gigaoctet)

[gbv-it]

The unit "Go" (Gigaoctet) was used at least once instead of the otherwise well known unit "GB" (Gigabyte).

Line 243 in e0c8403

* RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo

I think it would be better to always use the bytes unit instead of octets.
Especially since a few lines earlier in that same file 150MB and 1GB was mentioned.

So the line mentioned above would read: * RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3GB RAM for Odoo

I think today the unit octet (Ko, Mo, Go, etc.) is mostly used in the French language, in English and German (any almost all other languages) we are used to the unit byte (KB, MB, GB, etc.).
