connect: various changes to make namespaces for intentions work more like for other subsystems (#8194)
Highlights:

- add new endpoint to query for intentions by exact match

- using this endpoint from the CLI instead of the dump+filter approach

- enforcing that OSS can only read/write intentions with a SourceNS or
  DestinationNS field of "default".

- preexisting OSS intentions with now-invalid namespace fields will
  delete those intentions on initial election or for wildcard namespaces
  an attempt will be made to downgrade them to "default" unless one
  exists.

- also allow the '-namespace' CLI arg on all of the intention subcommands

- update lots of docs

# Consul Intention Match
Command: `consul intention match`
The `intention match` command shows the list of intentions that match
a given source or destination. The list of intentions is listed in evaluation
order: the first intention that matches a request would be evaluated.
The [check](/docs/commands/intention/check) command can be used to
check whether a connection would be authorized between any two services.
## Usage
Usage: `consul intention match [options] SRC_OR_DST`
`SRC` and `DST` can both take [several forms](/docs/commands/intention#source-and-destination-naming).
#### API Options
@include 'http_api_options_client.mdx'
#### Enterprise Options
@include 'http_api_namespace_options.mdx'
#### Intention Match Options
- `-destination` - Match by destination.
- `-source` - Match by source.
## Examples
```shell-session
$ consul intention match -source web
web => db (deny)
web => * (allow)
```
