* Support clearing an identity alias' custom_metadata
Previously, an update to an entity alias supported updating the
custom_metadata as long as the update was not empty, which makes it
impossible to clear the metadata values completely.
Fixes:
- empty custom_metadata parameters are honoured on entity alias update
- update related tests
- drop dependency on mapstructure
- reformat with gofumpt

* Add changelog
* Address review comments
* Add handling to aliasUpdate, some field renaming
* Update tests to work under new entity-alias constraint
