TrinoRestCatalog can ddos Identity Provider while refreshing auth token because of multiple cached session contexts

[varpa89]

When we create an Iceberg catalog with iceberg.rest-catalog.session option = NONE TrinoRestCatalog#convert method creates a new SessionContext on each hit with the random UUID. It lead to a situation when we cache iceberg AuthSession and cache key it this random UUID.
The problem is happening because in the background RestSessionCatalog tries to refresh the token for each key in the cache
