Update additional-parameters to be modifiable in the Dashboard UI

[mkuziemko]

Description

When I tried to install some of the manifests using Dashboard UI, there is a problem with providing the additional-parameters for them.

Expected behavior

I want to be able to change all of the additional-parameters using Dashboard UI.

Actual behavior

I can't provide some of the additional input due to reasons:

Unsupported field schema for field root: Missing items definition.
A mapping of tags to assign to all resources.

Steps to reproduce

1. Login to Dashboard UI (dashboard.capact.local)
2. Go to Redis instalattion (cap.interface.database.redis)
3. Click create Action with random instance name
4. In the tab ,,Advanced Settings" choose Redis Install Action with the cap.implementation.aws.redis.install:0.1.0 and click ,,Provide input"
