seperate cli and cmd main package

[iraj720]

hi @serathius
according to this issue that you have raised im trying to embed bbolt to etcdutl cli :
etcd-io/etcd#15760

i have seperated main functionalities of commands in cli package
now it will be easier for etcdutl to easily import this cli package and embed it to its own
and we wont face any versioning issue in there

if it looks good i can start to integrate etcdutl code based on this.
let me know if you have any better suggestion.
Thanks!

Looks good, cc @ahrtr

I am supportive to move commands into a separate package/directory, but I'd suggest to do such structure change after

• we cut the release-1.4 branch (pls see Plan to release bbolt 1.4.0 #553)
• we finish Migrate all commands to cobra style commands #472 (Will only be included in bbolt 2.0)

After above two things are done, then we can move all commands into a separate package/directory in bbolt 2.0. Afterwards, it would just need very minor change to get it embedded into etcdutl (etcd-io/etcd#15760)

@ahrtr
seems surgery commands and logger are ready to merge
so meanwhile we are merging them i will migrate all commands to cobra style.
then we can release 1.4 and merge this one then etcdutl will use this one.
is it ok?
