moved arm-appservice

[KarishmaGhiya]

Moving packages for arm-appservice from packages@Azure and putting them under an sdk directory.
A few changes that have been made:

The source code directory lib has been renamed to src
All the links in various files referencing lib have been updated to src
The paths of all the data-plane package under appservice service (@azure/arm-appservice) have been updated eg: packages/@azure/arm-appservice to the new structure path sdk/appservice/arm-appservice to follow the structure sdk/servicename/packagename
All the corresponding links in different files like package.json, etc have also been updated for the new structure path
I have also updated the path in README.md (typescript) for azure-rest-api-specs.

Please review Azure/azure-rest-api-specs#5608

@kpajdzik do you know why each management package has its own copy of the license file? There shouldn't be any reason we cannot share one for the entire repo.

[kpajdzik]

I don't think NPM is going to display correct license if it isn't shipped with the package.

I don't even know if the file is necessary for the standard licenses like MIT as the package.json simply has "license": "MIT", but the file does automatically get included in the package according to the spec https://docs.npmjs.com/files/package.json#files so if we did move it we would have to add an entry for it in our package.json manaully. For now lets leave it but it is something we should potentially clean-up at some point.

[kpajdzik]

Hmm, you may be right.

I filed issue #2150 to follow-up on this conversation.
