Fix FederatedStore checks for DYNAMIC_SCHEMA

[t92549]

Due to a partial implementation of #2008, currently FederatedOperationChains only validate the View if the graph does not have the DYNAMIC_SCHEMA trait:

Gaffer/store-implementation/federated-store/src/main/java/uk/gov/gchq/gaffer/federatedstore/operation/FederatedOperationChainValidator.java

Line 82 in 40bb337

if (!graph.getStoreTraits().contains(StoreTrait.DYNAMIC_SCHEMA)) {

Gaffer/store-implementation/federated-store/src/main/java/uk/gov/gchq/gaffer/federatedstore/util/FederatedStoreUtil.java

Line 134 in 40bb337

} else if (!graph.getStoreTraits().contains(StoreTrait.DYNAMIC_SCHEMA)) {

This trait only exists in the FederatedStore as its getTraits() implementation returns ALL_TRAITS. This effectively means that only FederatedStores and ProxyStores which point to a FederatedStore will not be validated here. However, this cannot be used going forward because:

• FederatedStore fixes introduced in the FederatedStore alpha mean it will no longer return ALL_TRAITS
• the getTraits function is being replaced by the Operation which behaves differently, instead of returning ALL_TRAITS it will use the FederatedGetTraitsHandler which correctly returns the traits that the FederatedStore's stores have

Therefore, before the getTraits/getStoreTraits function can be completely removed, this usage has to be replaced (under this ticket). This can be done in various ways:

• deciding on a different solution to the partial implementation of Remove view Edge Entity Validation for operations #2008: either by fully implementing it or reverting it perhaps?
• replacing the FederatedStore check with something else smarter than this DYNAMIC_SCHEMA trait check

A solution to this must be discussed, decided on and implemented before getTraits can be completely removed and it seems that it will be best to wait until the other FederatedStore changes first to do so.

The fix for this has to be smarter than just checking if the FederatedStore is assignable from the store in question, because it can also be valid for ProxyStores pointing to FederatedStores

Needs investigation to decide if this needs to stay in alpha5 or move to post V2. Might just result in code being deleted if it's not required

This will link in with #2581

Closed by #2915

The solution for this was to remove the getTraits method from Gaffer and use the operation instead, combined with removing the DYNAMIC_SCHEMA trait.
