$openldap::server::database::mirrormode does not enable olcMirrorMode

[jouveits]

The mirrormode parameter of the openldap::server::database resource type expects a string (or undef) but internally is tested against a boolean

The parameter is currently useless and does not trigger the olcMirrorMode option.

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 6.24
• Ruby: 2.5.9
• Distribution: Centos 7
• Module version: 4.0.0

How to reproduce (e.g Puppet code you use)

 openldap::server::database { 'dc=example,dc=com
    ensure     => present,
    rootdn     => 'admin',
    rootpw     => 'adminP.s5woRd',
    backend    => 'mdb',
    mirrormode => true,
    syncrepl   =>  #...,
  }

What are you seeing

No olcMirrorMode setting in the created database when this option is set to "true".

What behaviour did you expect instead

mirrormode should accept a boolean or undef.
