Add getName for the resource like blob/container/file

[sima-zhu]

Xstore team requests us to add a getName() API for resource name.
It will provide rich information for logging and debugging.

Better to have convenience feature of getting the parent as well.

What will getName() return? The blob's name on a BlobClient? Would we want a way to get access to the container name as well? For .NET we've got a work item to make our various UriBuilders public so customers can get access to any part of this info. Does that satisfy the same need?

We don't really need this in python, although it's not a bad thing to have either.
BlobClient.blob_name will return the name Similarly for others too.

After discussing with xstore team, we think the best route is to expose getname() on blobs as well as getContainerName() (and probably getName() on containers). This provides the ability to walk up and down the hierarchy.

The reason the "ContainerName" pattern is more interesting than "ParentName" is to accommodate ADLS scenarios which will be exposed through the same APIs.

As @rakshith91 mentions above - for Python we publicly expose all the path components on each of the clients as properties, for example:

BlobServiceClient.primary_hostname
BlobServiceClient.secondary_hostname
ContainerClient.container_name
BlobClient.container_name
BlobClient.blob_name
BlobClient.snapshot
