Alexander Bokovoy a57b665be0 idrange: only issue warning to restart services for a local range 
SIDGEN plugin only uses local ID ranges and thus a restart is really
needed only when a local range is added, modified or removed.

Also fix the SSSD warning because removal of any range requires restart
everywhere, not just on a specific server.

WARNING:
DNA plugin in 389-ds will allocate IDs based on the ranges configured for the
local domain. Currently the DNA plugin *cannot* be reconfigured itself based
on the local ranges set via this family of commands.
Manual configuration change has to be done in the DNA plugin configuration for
the new local range. Specifically, The dnaNextRange attribute of 'cn=Posix
IDs,cn=Distributed Numeric Assignment Plugin,cn=plugins,cn=config' has to be
modified to match the new range.

ID ranges
Manage ID ranges used to map Posix IDs to SIDs and back.
There are two type of ID ranges which are both handled by this utility:
- the ID ranges of the local domain
- the ID ranges of trusted remote domains
Both types have the following attributes in common:
- base-id: the first ID of the Posix ID range
- range-size: the size of the range
With those two attributes a range object can reserve the Posix IDs starting
with base-id up to but not including base-id+range-size exclusively.
Additionally an ID range of the local domain may set
- rid-base: the first RID(*) of the corresponding RID range
- secondary-rid-base: first RID of the secondary RID range
and an ID range of a trusted domain must set
- rid-base: the first RID of the corresponding RID range
- sid: domain SID of the trusted domain
and an ID range of a trusted domain may set
- auto-private-groups: [true|false|hybrid] automatic creation of private groups
EXAMPLE: Add a new ID range for a trusted domain
Since there might be more than one trusted domain the domain SID must be given
while creating the ID range.
ipa idrange-add --base-id=1200000 --range-size=200000 --rid-base=0 \\
--dom-sid=S-1-5-21-123-456-789 trusted_dom_range
This ID range is then used by the IPA server and the SSSD IPA provider to
assign Posix UIDs to users from the trusted domain.
If e.g. a range for a trusted domain is configured with the following values:
base-id = 1200000
range-size = 200000
rid-base = 0
the RIDs 0 to 199999 are mapped to the Posix ID from 1200000 to 13999999. So
RID 1000 <-> Posix ID 1201000
EXAMPLE: Add a new ID range for the local domain
To create an ID range for the local domain it is not necessary to specify a
domain SID. But since it is possible that a user and a group can have the same
value as Posix ID a second RID interval is needed to handle conflicts.
ipa idrange-add --base-id=1200000 --range-size=200000 --rid-base=1000 \\
--secondary-rid-base=1000000 local_range
The data from the ID ranges of the local domain are used by the IPA server
internally to assign SIDs to IPA users and groups. The SID will then be stored
in the user or group objects.
If e.g. the ID range for the local domain is configured with the values from
the example above then a new user with the UID 1200007 will get the RID 1007.
If this RID is already used by a group the RID will be 1000007. This can only
happen if a user or a group object was created with a fixed ID because the
automatic assignment will not assign the same ID twice. Since there are only
users and groups sharing the same ID namespace it is sufficient to have only
one fallback range to handle conflicts.
To find the Posix ID for a given RID from the local domain it has to be
checked first if the RID falls in the primary or secondary RID range and
the rid-base or the secondary-rid-base has to be subtracted, respectively,
and the base-id has to be added to get the Posix ID.
Typically the creation of ID ranges happens behind the scenes and this CLI
must not be used at all. The ID range for the local domain will be created
during installation or upgrade from an older version. The ID range for a
trusted domain will be created together with the trust by 'ipa trust-add ...'.
USE CASES:
Add an ID range from a transitively trusted domain
If the trusted domain (A) trusts another domain (B) as well and this trust
is transitive 'ipa trust-add domain-A' will only create a range for
domain A. The ID range for domain B must be added manually.
Add an additional ID range for the local domain
If the ID range of the local domain is exhausted, i.e. no new IDs can be
assigned to Posix users or groups by the DNA plugin, a new range has to be
created to allow new users and groups to be added. (Currently there is no
connection between this range CLI and the DNA plugin, but a future version
might be able to modify the configuration of the DNS plugin as well)
In general it is not necessary to modify or delete ID ranges. If there is no
other way to achieve a certain configuration than to modify or delete an ID
range it should be done with great care. Because UIDs are stored in the file
system and are used for access control it might be possible that users are
allowed to access files of other users if an ID range got deleted and reused
for a different domain.
(*) The RID is typically the last integer of a user or group SID which follows
the domain SID. E.g. if the domain SID is S-1-5-21-123-456-789 and a user from
this domain has the SID S-1-5-21-123-456-789-1010 then 1010 is the RID of the
user. RIDs are unique in a domain, 32bit values and are used for users and
groups.
