PR body:
"""
Refactoring cert-find to use API calls directly instead of using raw LDAP search.

Upstream ticket: https://pagure.io/freeipa/issue/6948

I removed the raw LDAP search and used the API directly. In the old code, the call `
self.obj._owners()` returns `service, hots and user`. However, when testing the code, only
the service was being used, so I made it only use the service API. 

If there another scenario where `user and host` are used, I thought to do something
like:

```python
for owner in self.obj._owners():
    api_name = owner.name
    response = api.Command[api_name+'_find'](options[api_name])
    ...  # continues
```
Is that correct?

Won't this cause it to not find certificates associated to users ?
Currently that works, this change is not replicating the same functionality of the
original code.

@simo5, it will. Same for hosts.

@felipevolpone, one possible correct fix would be to modify `cert._owners` to:
```python
    def _owners(self):
        for obj_name, pkey_name in [('user', None),
                                    ('host', None),
                                    ('service', 'krbprincipalname')]:
            obj = self.api.Object[obj_name]
            if pkey_name is None:
                pkey = obj.primary_key
            else:
                pkey = obj.params[pkey_name]
            yield obj, pkey
```
and replace all occurences of:
```python
    for owner in (...)._owners():
        ... owner.primary_key ...
```
with:
```python
    for owner, owner_pkey in (...)._owners():

Ok one thing was in the back of my mind and came up now, we need to keep in mind that
krbprincipalname can be multivalued. It won't affect this case (I think) but if we are
going to expose some new attribute we need to make sure users of the API are not tricked
into thinking it is alays the service's unique name (that's what krbCanonicalName
is for).

Remember taht you have to use 'exact=False' in the filter to perform substring
search for krbPrincipalName given the fact that (except for services) the principal is
constructed from primary key by appending realm (and prepending `host/` in the case of
hosts). This, however, opens a range of possibilities for new bug to creep in (considering
'tuser' is the owner but we have 'tuser1' and 'tuser2' in LDAP,
what will your search filter return?).

That's why I think this is not correct solution given we currently reference owners by
primary keys and not by principals (krbPrincipalName != primary key in most cases except
services without krbCanonicalName attribute). I am more inclined to @HonzaCholasta's
solution as it seems cleaner to me. An alternative is to report principals as cert owners,
which will break API, however.

"""
@felipevolpone, that is a bad idea. Calling the API instead of doing a direct LDAP search
would degrade performace (currently everything is done in a single LDAP search, with API
calls it will be *at least* one LDAP search per owner class) and offers less flexibility
(the current code allows you to find *any* LDAP entry which refers to a certificate, with
API calls you are limited to whatever is defined in the API).

The PR currently breaks the `--user` and `--host` options, because they no longer expect a
user name and host name, but principal names (as @martbab already pointed out).
