The license.txt file has been replaced with LICENSE for quite a while
now. INAL but it didn't seem accurate to say "hey, checkout license.txt
although there's no such file". Apart from this, there were
inconsistencies in the headers altogether...this change brings
consistency.

assets.json stores assets of all apps, so doesn't make sense to put it in frappe folder

* Remove six for PY2 compatability since our dependencies are not, PY2
  is legacy.
* Removed usages of utils from future/past libraries since they are
  deprecated. This includes 'from __future__ ...' and 'from past...'
  statements.
* Removed compatibility imports for PY2, switched from six imports to
  standard library imports.
* Removed utils code blocks that handle operations depending on PY2/3
  versions.
* Removed 'from __future__ ...' lines from templates/code generators
* Used PY3 syntaxes in place of PY2 compatible blocks. eg: metaclass

terminal sizes

* Deprecate --make-copy and --restore options for build in favour of --hard-link
* Show feedback for linking/copying application assets

public folder already has a symlink to node_modules. So we can just
check if the realpath already exists and ignore copying it again if the
same exists

* Use raw text for regex patterns to avoid Deprecation warnings

- Add --apps option
- Add --production option
- Add --apps option for bench watch command
- Add --skip_frappe in esbuild
