Allow to update interface operations on a component instance, which includes adding/removing input assignments.

TOSCA allows to insert a dynamic input to node interface operations: https://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.3/os/TOSCA-Simple-Profile-YAML-v1.3-os.html#_Toc26969435

None of the pre-defined TOSCA interfaces operations have inputs, see 5.8 Interface Types:

• tosca.interfaces.Root
• tosca.interfaces.node.lifecycle.Standard
• tosca.interfaces.relationship.Configure

So the inputs are created in a node_template, without the need of pre-defining it. Also the inputs seems to be environment variables, so we should consider to be a string/string key/value pair.

For example, when using script artifacts, input values are passed as environment variables within the execution environments in which the scripts associated with lifecycle operations are run.

 We are aiming to have a operation definition with input assignments:

3.6.17.2.3 Extended notation for use in Template definitions

Where each input is a 3.6.11 Property assignment, which we can consider only string values.

<property_name>: <property_value> | { <property_value_expression> }

And the operation implementation definition is the short notation for a single artifact:

3.6.16.2.1 Short notation for use with single artifact

implementation: <primary_artifact_name>
