Martin Basti 0accf8ccb6 fix upgrade: wait for proper DS socket after DS restart 
DS restart executed by upgrade plugin causes that upgrade framework
is waiting for the improper socket. It leads to TimeoutError because
DS is not listening on 389 port during upgrade. This commit fixes the issue.

Data Structure Example:
-----------------------
dn_by_rdn_count = {
3: 'cn=config,dc=example,dc=com':
4: 'cn=bob,ou=people,dc=example,dc=com',
}
all_updates = [
{
'dn': 'cn=config,dc=example,dc=com',
'default': [
dict(attr='attr1', value='default1'),
],
'updates': [
dict(action='action', attr='attr1', value='value1'),
dict(action='replace', attr='attr2', value=['old', 'new']),
]
},
{
'dn': 'cn=bob,ou=people,dc=example,dc=com',
'default': [
dict(attr='attr3', value='default3'),
],
'updates': [
dict(action='action', attr='attr3', value='value3'),
dict(action='action', attr='attr4', value='value4'),
}
}
]
Please notice the replace action requires two values in list
The default and update lists are "dispositions"
Plugins:
Plugins has to be specified in update file to be executed, using
'plugin' directive
Example:
plugin: update_uniqueness_plugins_to_new_syntax
Each plugin returns two values:
1. restart: dirsrv will be restarted AFTER this update is
applied.
2. updates: A list of updates to be applied.
The value of an update is a dictionary with the following possible
values:
- dn: DN, equal to the dn attribute
- updates: list of updates against the dn
- default: list of the default entry to be added if it doesn't
exist
- deleteentry: list of dn's to be deleted (typically single dn)
For example, this update file:
dn: cn=global_policy,cn=$REALM,cn=kerberos,$SUFFIX
replace:krbPwdLockoutDuration:10::600
replace: krbPwdMaxFailure:3::6
Generates this list which contain the update dictionary:
[
{
'dn': 'cn=global_policy,cn=EXAMPLE.COM,cn=kerberos,dc=example,dc=com',
'updates': [
dict(action='replace', attr='krbPwdLockoutDuration',
value=['10','600']),
dict(action='replace', attr='krbPwdMaxFailure',
value=['3','6']),
]
}
]
Here is another example showing how a default entry is configured:
dn: cn=Managed Entries,cn=etc,$SUFFIX
default: objectClass: nsContainer
default: objectClass: top
default: cn: Managed Entries
This generates:
[
{
'dn': 'cn=Managed Entries,cn=etc,dc=example,dc=com',
'default': [
dict(attr='objectClass', value='nsContainer'),
dict(attr='objectClass', value='top'),
dict(attr='cn', value='Managed Entries'),
]
}
]
Note that the variable substitution in both examples has been completed.
Either may make changes directly in LDAP or can return updates in
update format.
