Add option in RODA CLI to change LDAP admin password

[chalkos]

Running RODA as CLI supports changing the admin user password (for uid=admin,ou=users,dc=roda,dc=org) but not the LDAP admin password (for uid=admin,ou=system)

When the LDAP server is exposed the admin password should be different than the default ("roda").

---

Also check if RODA (during startup, when LDAP data has not been created) initializes LDAP using the LDAP admin password specified in roda-core.properties:

core.ldap.adminPassword

If it doesn't, it should be fixed (in this issue or in a new one).

As a workaround, the LDAP admin password can be changed using an interactive ldap session:

ldapmodify -v -h localhost -p 10389 -D "uid=admin,ou=system" -w "roda"

The following line should appear:

ldap_initialize( ldap://localhost:10389 )

Write:

dn: uid=admin,ou=system
changetype: modify
replace: userPassword
userPassword: <newPassword>

Pressing ENTER twice will apply the changes and output something like this:

replace userPassword:
        <newPassword>
modifying entry "uid=admin,ou=system"
modify complete

Use CTRL+D to quit the interactive session.
