feat: add duration to affected releases on sync

[AlexAxenti]

The purpose of this feature is to show the duration it took to update or delete each release when a sync, destroy, or apply command is called. Below are some examples:

Old display of affected releases:

UPDATED RELEASES:
NAME                CHART           VERSION
release-one         charts/test       0.1.0
release-two         charts/test       0.1.0 

DELETED RELEASES:
NAME
release-three
release-four

FAILED RELEASES:
NAME
release-five
release-six

New display of affected releases:

UPDATED RELEASES:
NAME              CHART           VERSION     DURATION
release-one       charts/test     0.1.0             8s
release-two       charts/test     0.1.0            13s

DELETED RELEASES:
NAME              DURATION
release-three           0s
release-four            0s

FAILED RELEASES:
NAME              CHART           VERSION  
release-five      charts/test       0.1.0      
release-six       charts/test       0.1.0

For people who uses helmfile with many and complex releases, with several helm level install/uninstall hooks and also helmfile level sync/delete hooks, it would be nice to have a summary at the end with how much time was spent in processing each individual release.

Having this information in a CI loop, for example, allows me to find out which of my releases is the actual bottleneck and deserves more optimization.

/cc @mumoshu I think this is a good idea. I saw the code. The logic is straightforward. and almost all changed files are test files.

/cc @xiaomudk waiting for your review.

[mumoshu]

I'll review this asap! Thanks a lot for your efforts!

[xiaomudk]

@AlexAxenti please fix DCO~

@felipecrs need your help.

@felipecrs need your help.

Yeah.. there is not much I can do now unfortunately.

But thanks a lot anyway! Let's wait for @AlexAxenti.

@xiaomudk @yxxhero Hey! I think @AlexAxenti has already signed-off every commit he added and it would be 8cae3e5 which made DCO check unhappy!

Also, 8cae3e5 broken tests and other references to former "Duration" which is now "duration" so we'd better check this branch out locally and amend the commit to include other fixes, along with a sign-off.

[felipecrs]

@AlexAxenti and I can also fix this tomorrow, if you prefer.

[AlexAxenti]

Just fixed the errors caused by the incorrect Duration being referenced as well as signed-off the commits, hopefully should be good now.
