Allow 'web' as a hard coded resource name

[theunrepentantgeek]

What this PR does

Some services hardcode names into their URLs, such as default here:

blobService/default/containers/{containerName}

When we construct the resource type identifier for those resources, we don't want to include those - for this example, we want blobService/containers not blobService/default/containers.

While importing Microsoft.Web/sites/sourcecontrols Nishant Shekhar encountered this error:

could not create fully qualified ARM ID, had 2 azureNames and 3 resourceTypes. 
azureNames: ["aso-sample-function" "web"] 
resourceTypes: ["sites" "sourcecontrols" "web"]

which I traced down to the presence of the hard coded name web in this URL:

/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{name}/slots/{slot}/sourcecontrols/web

I've refactored the code to allow for web as a hard coded name in addition to default, and to raise an error should another form of hard coded name be encountered.

Special notes

I combined several existing tests into a single table test.

How does this PR make you feel?
