This resource is the first which makes use of the new Riviera library
(at https://github.com/jen20/riviera), so there is some additional set
up work to add the provider to the client which gets passed among
resources.
Using EnvDefaultFunc with a default of empty string causes the
validation which would ordinarily be performed by `Required: true` in
the schema to not have any effect. Instead validate the configuration
used to produce the ARM client before attempting to use it during
provider configuration.
These resources use ARM to get keys for the storage API, but then use
the storage REST API as per the ASM provider. The code is significantly
reworked with better logging and error handling. The key functions can
be reused for queues and file storage resources when they get added.
This is an unusual resource (so far) in that it cannot be created in one
call, and instead must be created and the modified to set some of the
parameters.
We use the pollIndefinitelyWhileNeeded function which will continue to
poll Azure RM operation monitoring endpoints until an error is reported
or the operation meets one of the given status codes. The function was
originally part of this feature but was separated out in order to
unblock other work.
Currently there is no support for the "custom_domain" section of the
storage account API. This was originally present and was later taken out
of the scope of the storage account resource in order that the following
workflow can be used:
1. Create storage account
2. Create DNS CNAME entry once the account name is known
3. Create custom domain mapping
This adds a pollIndefinitelyWhileNeeded function which will continue to
poll Azure RM operation monitoring endpoints until an error is reported
or the operation meets one of the given status codes. This may need
revisiting at some point in the future.
When parsing resource IDs (probably incorrectly since they are URIs and
should therefore be opaque), we need to look for "resourcegroups" in
addition to "resourceGroups" because the Azure CDN resources return that
in their URIs.
Unfortunately the casing semantics of the rest of the string are not
clear, so downcasing the entire URI is probably best avoided. This is a
fix for a single case.
