Florence Blanc-Renaud 794b2c32f6 User and groups: rename with --setattr must check format 
There are 2 possible methods to rename users and groups:
- either use ipa user|group-mod oldname --rename newname
- or use settattr:
   ipa user-mod oldname --setattr uid=newname
   ipa group-mod oldname --setattr cn=newname

The first method validates the new name but the second method
doesn't. Add a validation to make both methods consistent

Fixes: https://pagure.io/freeipa/issue/9396

Groups of users
Manage groups of users, groups, or services. By default, new groups are POSIX
groups. You can add the --nonposix option to the group-add command to mark a
new group as non-POSIX. You can use the --posix argument with the group-mod
command to convert a non-POSIX group into a POSIX group. POSIX groups cannot be
converted to non-POSIX groups.
Every group must have a description.
The group name must follow these rules:
- cannot contain only numbers
- must start with a letter, a number, _ or .
- may contain letters, numbers, _, ., or -
- may end with a letter, a number, _, ., - or $
POSIX groups must have a Group ID (GID) number. Changing a GID is
supported but can have an impact on your file permissions. It is not necessary
to supply a GID when creating a group. IPA will generate one automatically
if it is not provided.
Groups members can be users, other groups, and Kerberos services. In POSIX
environments only users will be visible as group members, but nested groups and
groups of services can be used for IPA management purposes.
EXAMPLES:
Add a new group:
ipa group-add --desc='local administrators' localadmins
Add a new non-POSIX group:
ipa group-add --nonposix --desc='remote administrators' remoteadmins
Convert a non-POSIX group to posix:
ipa group-mod --posix remoteadmins
Add a new POSIX group with a specific Group ID number:
ipa group-add --gid=500 --desc='unix admins' unixadmins
Add a new POSIX group and let IPA assign a Group ID number:
ipa group-add --desc='printer admins' printeradmins
Remove a group:
ipa group-del unixadmins
To add the "remoteadmins" group to the "localadmins" group:
ipa group-add-member --groups=remoteadmins localadmins
Add multiple users to the "localadmins" group:
ipa group-add-member --users=test1 --users=test2 localadmins
To add Kerberos services to the "printer admins" group:
ipa group-add-member --services=CUPS/some.host printeradmins
Remove a user from the "localadmins" group:
ipa group-remove-member --users=test2 localadmins
Display information about a named group.
ipa group-show localadmins
Group membership managers are users or groups that can add members to a
group or remove members from a group.
Allow user "test2" to add or remove members from group "localadmins":
ipa group-add-member-manager --users=test2 localadmins
Revoke membership management rights for user "test2" from "localadmins":
ipa group-remove-member-manager --users=test2 localadmins
External group membership is designed to allow users from trusted domains
to be mapped to local POSIX groups in order to actually use IPA resources.
External members should be added to groups that specifically created as
external and non-POSIX. Such group later should be included into one of POSIX
groups.
An external group member is currently a Security Identifier (SID) as defined by
the trusted domain. When adding external group members, it is possible to
specify them in either SID, or DOM\\name, or name@domain format. IPA will attempt
to resolve passed name to SID with the use of Global Catalog of the trusted domain.
Example:
1. Create group for the trusted domain admins' mapping and their local POSIX group:
ipa group-add --desc='<ad.domain> admins external map' ad_admins_external --external
ipa group-add --desc='<ad.domain> admins' ad_admins
2. Add security identifier of Domain Admins of the <ad.domain> to the ad_admins_external
group:
ipa group-add-member ad_admins_external --external 'AD\\Domain Admins'
3. Allow members of ad_admins_external group to be associated with ad_admins POSIX group:
ipa group-add-member ad_admins --groups ad_admins_external
4. List members of external members of ad_admins_external group to see their SIDs:
ipa group-show ad_admins_external
