f2fs: change preferred options

[AleVul]

This PR changes preferred options for f2fs.

This set of options was inspired by ArchLinux's recommended options with some changes.

Rationale for some of the options:

• compress_algorithm=lz4 - compression by itself is useful to prolong flash drive life. The trouble I had was to figure out what algorithm to use for desktop usage. There are several options, generally (from what I managed to find) people tend to use either zstd or lz4 for filesystem compression. Judging by this benchmark lz4 is faster at (de)compression but has a lower compression ratio. My thinking here is that this will be less noticeable for end user when reading/writing files. Note that arch linux recommends zstd with compression level 6, I do not insist on using lz4, and I can change it for something else if a compelling argument is provided.
• nodiscard - periodic trim is enabled on ubuntu since 18.04 (and by extension on pop!_os?). This options disables continuous trim. Other options are just tweaks to garbage collection, more info about them here and reducing writes for file access times.

Some of the features of f2fs must be enabled at mkfs time so that the driver could use the options above. More about this features can be found in man pages.

Is there a reason to disable discard?

Is there a reason to disable discard?

The only reason is to enable periodic trim for f2fs filesystems. See this and this

Also if you try to run the install again you need to use fdisk to delete all the partitions, and then use mkfs to make the whole drive one ext4 partition.

By default, mkfs.f2fs will not write to the device if it suspects that there is a filesystem or partition table on the device already. If this is desired, we could use -f switch so that mkfs.f2fs would attempt to overwrite.

@AleVul I did a quick test with -f and it does resolve that issue. It might be good to have as it will make further testing simpler when a clean install is needed.
