SELinux Policy: system_u:system_r:cachefiles_kernel_t:s0

**What I'd like:**
I would like to enable fscache in order to allow caching of NFS files. Currently my issue is that on running cachefilesd I either receive:

```
About to bind cache
CacheFiles bind failed: errno 13 (Permission denied)
```

or

```
About to bind cache
CacheFiles bind failed: errno 22 (Invalid argument)
```

The last happens if I specify, which should be the correct selinux policy to reference

```
secctx system_u:system_r:cachefiles_kernel_t:s0
```

It looks like the policy is missing in bottlerocket os:

```
[root@admin]# seinfo -t | grep cache
cache_t
```

I appreciate if that policy could be added.
