gofumpt (mvdan.cc/gofumpt) is a fork of gofmt with stricter rules.
Brought to you by
git ls-files \*.go | grep -v ^vendor/ | xargs gofumpt -s -w
Looking at the diff, all these changes make sense.
Also, replace gofmt with gofumpt in golangci.yml.

Generalize the libct/getValueFromCgroup() as fscommon.GetValueByKey(),
and document it.
No changes other than using fscommon.ParseUint to convert the value.

1. This is the only function in the package with Get prefix
that does not read a file (but parses a string). Rename
accordingly, and convert the callers.
GetCgroupParamKeyValue -> ParseKeyValue
2. Use strings.Split rather than strings.Fields. Split by a space
is 2x faster, plus we can limit the splitting. The downside is
we have to strip a newline in one of the callers.
3. Improve the doc and the code flow.
4. Fix a test case with invalid data (spaces at BOL).

1. Use GetCgroupParamString as the initial part of both functions are
the same and we can reuse it. This also gives us whatever security
measures GetCgroupParamString has (see previous commit).
2. Fix the error wrapping to not add the value, as it is already a part
of the error returned by ParseUint.
3. Improve docstring.

1. Use own ReadFile wrapper instead of ioutils.ReadFile.
This makes it use the security measures of ReadFile.
2. Improve doc.

2. Fix wrapping the error to not have the value as it's already
part of the error returned from ParseUint.
3. Fix/improve doc.

split fs2 package from fs, as mixing up fs and fs2 is very likely to result in
unmaintainable code.
