* Make os_profile optional #11147
* Test for optional os_profile and fix resourceArmVirtualMachineRead
* Updating to match other optionally-required fields
Found as part of #15065, when there is no default VPC, Terraform will
throw a panic. This prevents that as a user should never get that

* provider/datadog: make datadog_user verified a computed attribute
It's read-only and generates supurious diffs for verified users.
* Update resource_datadog_user.go
* Fix issues in Cloudwatch Log Group tag
1) Removing tags from terraform doesn’t actually get removed in AWS
2) Trying to update a tag with empty value (“”) to a non-empty value
causes terraform to loop forever
The issue was caused by a mixup of using tag values where tag name
should have used and is corrected in this patch.
This patch also removes the comparison of old and new tag values,
because AWS api takes care of updates by itself and there is no need to
perform an unnecessary UnTag API to update an existing tag value
* Updated the test cases to cover the removal and empty update scenarios
* core: Add 'UserAgentString' helper function to generate a standard UserAgent string. Example generation: 'Terraform 0.9.7-dev (go1.8.1)'
* provider/openstack: Add Terraform version to UserAgent string
* Resolved merge conflicts
* Changes conforming to HashiCorp guidelines and additional bug fixes
* Rebase merge
* Rebase merge
* Merging changes
* Changes to tests and code constructs
Previously `ModifyInstanceAttribute` permissions were required on creating a new instance with an unmodified `source_dest_check` attribute, as we forced the `ModifyInstanceAttribute` set on a new AWS instance.
This change only calls `ModifyInstanceAttribute` if `source_dest_check` was changed from default on a new instance, or if `source_dest_check` was modified.

* vendor: Add gophercloud/routerinsertion package and update
gophercloud/firewall to support router insertion
* provider/openstack: Add support for associating
`openstack_fw_firewall_v1` resources with router(s).
Added `associated_routers` and `no_routers` arguments.
* website: Add documentation for `associated_routers`and `no_routers` arguments on `openstack_fw_firewall_v1` resource.
* provider/openstack: Add `AddValueSpecs` function and refactor existing
uses.
If more than one of the allowed targets is specified in an `aws_route`
resource, we should provide an error message that does not include
`route_table_id` as a valid target, since `route_table_id` is actually
a required argument.
