registerSchema creates some indirection which is not necessary in this
case. newDBSchema can call each of the tables.
Enterprise tables can be added from the existing withEnterpriseSchema
shim.
Deleting from memdb inside an interation can cause a panic from Iterator.Next. This
case is technically safe (for now) because the iterator is using the root radix tree
not a modified one.
However this could break at any time if someone adds an insert or delete to the coordinates table
before this place in the function.
It also sets a bad example, because generally deletes in an interator are not safe. So this
commit uses the pattern we have in other places to move the deletes out of the iteration.
Using withEnterpriseSchema() we can apply any enterprise schema changes
with a single shim, removing the need to duplicate all of the table
definitions.
Also move all the catalog schemas to a new file to shrink catalog.go a bit.
* Fix bug in usage metrics that caused a negative count to occur
There were a couple of instances were usage metrics would do the wrong
thing and result in incorrect counts, causing the count to attempt to
decrement below zero and return an error. The usage metrics did not
account for various places where a single transaction could
delete/update/add multiple service instances at once.
We also remove the error when attempting to decrement below zero, and
instead just make sure we do not accidentally underflow the unsigned
integer. This is a more graceful failure than returning an error and not
allowing a transaction to commit.
* Add changelog
These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.
Also remove some unused methods.
Previously the tokens would fail to insert into the secondary's state
store because the AuthMethod field of the ACLToken did not point to a
known auth method from the primary.
Add a skip condition to all tests slower than 100ms.
This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.

With this change:
```
$ time go test -count=1 -short ./agent
ok github.com/hashicorp/consul/agent 0.743s
real 0m4.791s
$ time go test -count=1 -short ./agent/consul

```
The Catalog, Config Entry, KV and Session resources potentially re-validate the input as its coming in. We need to prevent snapshot restoration failures due to missing namespaces or namespaces that are being deleted in enterprise.
1. do a state store query to list intentions as the agent would do over in `agent/proxycfg` backing `agent/xds`
2. upgrade the database and do a fresh `service-intentions` config entry write
3. the blocking query inside of the agent cache in (1) doesn't notice (2)
Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.
The output of the previous assertions made it impossible to debug the tests without code changes.
With go-cmp comparing the entire slice we can see the full diffs making it easier to debug failures.
Required also converting some of the transaction functions to WriteTxn
because TxnRO() called the same helper as TxnRW.
This change allows us to return a memdb.Txn for read-only txn instead of
wrapping them with state.txn.
