Rearranging Interface app module code.

Working code for creating vlan, adding tagged/untagged port to vlan, and deletion of vlan.

Refactoring intf_app.go to accomodate all the interface types.wq

Support for access-vlan delete, working vlan create, tagged/untagged
add, access/trunk mode config alone and removal of untagged.

CLI and python binding completion with testing and untagged vlan config validation.

Tested and working code for all the VLAN test cases except tagged VLAN delete, with validations added.x

Fixed the build failure.

Correcting the valid error message to be thrown to front-end.

Rearranging the get code, cleanup and add the support for vlan-info.

Tested the vlan-list get support for all the interfaces and specific
interface

Working code for get-support for individual attributes.

Working code for config, add/remove member-ports, and get support.

Cleanup of the comments and logs.

Cleanup of the code.

Added the copyright header for new files.

Support for ignoring request for same config and for meaningful error
for tagged/untagged configs to front-end.

Support for CLI support-VLAN after merging with cleaned up CLI skeleton changes.

Support for #show vlan [<id>] command using sonic-yang.

Support for deletion of trunk-vlan instance, its associated CLI support and bug fix in #show vlan command.

Cleanup of the yang files in models/yang directory and cvl directory

Bugfixes for individual get and panic warnings.

Support for state container attribute get for VLAN

Added a note for initializing DS at the beginning.
