File _constraints of Package mongodb

<!--
Thanks Normand of the mailing list!
Example:        https://build.opensuse.org/package/view_file/server:database/mongodb/_constraints?expand=1
Reference page: https://openbuildservice.org/help/manuals/obs-reference-guide/cha.obs.build_job_constraints.html

For checking if the constraints can be verified easily, I used multiple times 'osc checkconstraints'.
First I checked for the disk size, then the memory.

    MongoDB seems to require just lots of build space, but not so much of
    memory. So, just request the proper amount of disk and that's it!
    
    Old requirements
    <disk>
      <size unit="G">100</size>
    </disk>
    <physicalmemory>
      <size unit="G">8</size>
    </physicalmemory>

    Seems now it is quite memory hungry, so ensure we have enough RAM.
    The constraint below bumps up all machines to the juicy ones.

    <physicalmemory>
      <size unit="G">17</size>
