Add storeManifest boolean property to allow persisting manifest.json between executions

[anna-geller]

Feature description

dbt allows rebuilding only models which have changed since the last run:

dbt build --select state:modified+ --defer

To know which models have been modified, the user would need to store the manifest.json.

We can store that in the KV store automatically to allow that pattern.

Possible implementation

if the user sets the storeManifest to true, then Kestra would:

• store the manifest file in the KV Store after each run
• before starting a new run, load the manifest file so dbt can compare the existing one with the new "state" of the dbt models
