RPCCapabilities class doesn't display properly for mergeable cases. (side-effect: the equal action is wrong.)

Describe the bug
RPCCapabilities class doesn't display properly for mergeable cases. (side-effect: the equal action is wrong.)

To Reproduce
// Affected commit: V10
i.e., https://github.com/eclipse-volttron/volttron-core/blob/v10/src/volttron/types/auth/authz_types.py

// Steps to reproduce the behavior:
Use the following code snippet to reproduce the error

import volttron.types.auth.authz_types as authz

rpc_cap4 = authz.RPCCapability("id2.rpc2")
rpc_cap4.add_param_restrictions("p2", "v2")
rpc_cap4.add_param_restrictions("id", "id2")

rpc_cap1 = authz.RPCCapability("id.rpc1")
rpc_cap2 = authz.RPCCapability("id2.rpc2", {"id": "id2", "param2": "v2"})

# print(f"{rpc_obj_list_2=}")
print(f"{rpc_cap1=}")
print(f"{rpc_cap2=}")
print(f"{rpc_cap4=}")

rpc_obj_list_2 = authz.RPCCapabilities([rpc_cap1, rpc_cap2, rpc_cap4])
# rpc_obj_list_2 = authz.RPCCapabilities([rpc_cap1, rpc_cap2,])
rpc_obj_list_3 = authz.RPCCapabilities()
rpc_obj_list_3.add_rpc_capability(rpc_cap1)
rpc_obj_list_3.add_rpc_capability(rpc_cap2)
rpc_obj_list_3.add_rpc_capability(rpc_cap4)

print(f"{rpc_obj_list_2=}")
print(f"{rpc_obj_list_3=}")
print(f"{(rpc_obj_list_2==rpc_obj_list_3) =}")

result

rpc_cap1=RPCCapability(resource='id.rpc1', param_restrictions={})
rpc_cap2=RPCCapability(resource='id2.rpc2', param_restrictions={'id': 'id2', 'param2': 'v2'})
rpc_cap4=RPCCapability(resource='id2.rpc2', param_restrictions={'p2': 'v2', 'id': 'id2'})
rpc_obj_list_2=RPCCapabilities(rpc_capabilities=[RPCCapability(resource='id.rpc1', param_restrictions={}), RPCCapability(resource='id2.rpc2', param_restrictions={'id': 'id2', 'param2': 'v2', 'p2': 'v2'}), RPCCapability(resource='id2.rpc2', param_restrictions={'p2': 'v2', 'id': 'id2'})], _rpc_dict={'id.rpc1': {}, 'id2.rpc2': {'p2': 'v2', 'id': 'id2'}})
rpc_obj_list_3=RPCCapabilities(rpc_capabilities=[RPCCapability(resource='id.rpc1', param_restrictions={}), RPCCapability(resource='id2.rpc2', param_restrictions={'id': 'id2', 'param2': 'v2', 'p2': 'v2'})], _rpc_dict={'id.rpc1': {}, 'id2.rpc2': {'id': 'id2', 'param2': 'v2', 'p2': 'v2'}})
(rpc_obj_list_2==rpc_obj_list_3) =False

Expected behavior
rpc_obj_list_2 should display the same as rpc_obj_list_3, i.e.,
RPCCapabilities(rpc_capabilities=[RPCCapability(resource='id.rpc1', param_restrictions={}), RPCCapability(resource='id2.rpc2', param_restrictions={'id': 'id2', 'param2': 'v2', 'p2': 'v2'})], _rpc_dict={'id.rpc1': {}, 'id2.rpc2': {'id': 'id2', 'param2': 'v2', 'p2': 'v2'}}). However, it has repetitive items (i.e., RPCCapability(resource='id2.rpc2', param_restrictions={'id': 'id2', 'param2': 'v2', 'p2': 'v2'}), RPCCapability(resource='id2.rpc2', param_restrictions={'p2': 'v2', 'id': 'id2'}))

In addition, (rpc_obj_list_2==rpc_obj_list_3) should be True.

@kefeimo None of the list type data classes (pubsubcapabilities, rpc capabilities, agents etc.) have equals or hash method overwritten. I simply didn't have a need to compare objects directly using custom_list_type_objec1 == custom_list_type_object2. If you overwrite equals, you have to overwrite hash method too. I have to loop through these objects anyway in order to handle string type capabilities (say "vip1.rpc1") and nested dictionary type capabilities (say {"vip2.rpc2": {"param1":"value1"}}) differently when comparing or merging. So simply did not have a need for these methods. Nor did I implement str or repr. If there is a need, we can certainly add these methods

Just adding a bit more context- these data class are for VOLTTRON core internal purposes only - ie. only admin role can call the AUTH service rpc method that in turn call the data class methods. That is also one of the reason for adding methods as need - i.e. iteratively - as we add end user user feature/vctl subparsers.
