Request: input sanitization on account name

[1stewart]

Microsoft's Storage Accounts only support lowercase and numbers in names: https://docs.microsoft.com/en-us/azure/azure-resource-manager/management/resource-name-rules#microsoftstorage

Supplying invalid values (accidentally since I missed the space!) results in attempting to use the value, instead of validating it before submitting, and the response 'Invalid account or key', though I think it'd be more user friendly if the account name box failed regex validation. There may be a reason to support other characters for custom domains, but since both requests are defaulting to the normal endpoints I think the logic could be split if there's a suffix.

Thank you @1stewart for this report.
I have been working on the internal support for custom domains, so I'll take a look at your report with that in mind.
