This allows terraform users to manage single key/value items within the
project metadata map, rather than the entire map itself.
* Update CHANGELOG.md
* Add details about import
* Add charset and collation to google_sql_database.
* Add documentation for charset, collation attributes.
* Extend the existing acceptance test to also cover charset and collation.
* Charset and collation always have a value present. Also inline.
* Move charset and collation to optional arguments.
* Add charset and collection to the example.
* Document charset and collation defaults.
* Keep TestAccGoogleSqlDatabase_basic as is, add TestAccGoogleSqlDatabase_update.
* Add import support for google_compute_image.
* Added comment explaning why we set the create_timeout in the import state method
* Don't ForceNew for create_timeout field
* Update image name in import documentation
* update compute instance docs to use new boot and scratch disk attributes, document attached_disk
* Update compute instance tests to mostly use new boot and scratch disk attributes
* Fix encryption test by setting values in state from what was there before
* Add scratch_disk property to google_compute_instance
* docs for scratch_disk
* limit scope of scratchDisks array by using bool, test formatting
* add slash back to disk check
* Add boot_disk property to google_compute_instance
* docs for boot_disk
* limit scope of bootDisk, use bool instead
* test formatting
* make device_name forcenew, add sha256 encryption key
* compute_disk: update image in test
* disk_image: add default type, make size computed
* compute_dis: wait on disk size operations to complete before moving on
* update docks on the image
* Add compute_backend_service import support
* Fixed the nit
* Made example names a bit more intuitive
* Use underscores wherever possible instead of dashes
* Mention PostgreSQL in sql_database_instance docs
As mentioned in hashicorp/terraform#12617 the
google_sql_database_instance resource already supports `POSTGRES_9_6` as
`database_version`, it is just undocumented so far.
* Make naming of google_sql_database consistent
Looks like this is a relict from some copy & paste from
`google_storage_*` while writing the docs for `google_sql_database`.
* Note that Postgres support is still BETA
