Sort RewardDelegators when marshaling a validator

[msmania]

Description

This is a fix for a regression introduced by #1581.

When a node stores a validator with the new RewardDelegators field, its marshaled product is not deterministic because the order of map iteration is not deterministic. As a result, the merkle tree of application.db can differ between nodes, leading to consensus failure.

The proposed fix is to sort the keys of RewardDelegators by using the stable marshaler.

This pull request includes changes to the nodes.proto file and a file diff.

The changes in the nodes.proto file include:

• Added an option stable_marshaler with a value of true. This option is used to make the order of RewardDelegators deterministic.
• Updated the Address field to include additional options (gogoproto.casttype), (gogoproto.moretags), and (gogoproto.jsontag).
• Updated the PublicKey field to include additional options (gogoproto.moretags) and (gogoproto.jsontag).
• Updated the jailed field to include an additional option (gogoproto.jsontag).

The file diff includes the following changes:

• Imported the "encoding/hex", "math/rand", "reflect", "strconv", and "time" packages.
• Added a test case for marshalling RewardDelegators.
• Added the "Test_Marshal_RewardDelegators" function.
• Created variables and constants within the test function.
• Generated random numbers to be used as reward delegator addresses.
• Created and initialized a map, "delegatorMap", with random numbers as keys and their corresponding modulo 10 values as values.
• Created a "Validator" struct with various fields and assigned values to them.
• Marshaled the validator struct and ensured that the resulting hash is the same for every iteration of the test.

Please let me know if there is anything specific you would like me to focus on.
