mirror: do not let curtin decide the URL of the security archive
When the URL of the security archive is unset, curtin will set it to the
URL of the primary archive.
This is not the behavior we want for Ubuntu installations. On amd64 (and
i386), the URL of the security archive should be set to
http://security.ubuntu.com/ubuntu
On other architectures, it should be set to
http://ports.ubuntu.com/ubuntu-ports

filesystem: store the actual size in bytes alongside the human readable size
Currently, the partition form stores the size as a human readable value.
(e.g., 123456K, 1.1G, 1.876G, 100G). When we exit the size field (i.e., upon
losing focus), we convert the value to a number of bytes and then align
it up to the nearest MiB (or whatever the alignment requirement is).
Unfortunately, after computing the aligned value, we turn it back into a
human-readable string and store it as is. It is not okay because the
conversion does not ensure that the alignment requirement is still
honored.
For instance, if the user types in 1.1G, we do the following:
* convert it to a number of bytes -> 1181116006.4 (surprise, it is not
even an integer).
* round it up to the nearest MiB -> 1181745152 (this is the correct
value)
* transform it into a human readable string and store it as is -> 1.1G
- which actually corresponds to the original value.
This leads to an exception later when creating the partition:
File "subiquity/models/filesystem.py", line 1841, in add_partition
raise Exception(
Exception: ('size %s or offset %s not aligned to %s', 1181116006, 1048576, 1048576)
Fixed by storing the actual size as a number of bytes - alongside the
human readable size.
