This task is to update prefix of Spring config variables for DMI Rest client. They should go under ncmp.dmi.httpclient, to be consistent with other NCMP variables. Example application.yml:

ncmp:
  dmi:
    httpclient:
      maximumConnectionsPerRoute: 50
    auth:
      username: dmiUser

A/C:

• Spring config variables for DMI HttpClient should be under ncmp.dmi.httpclient
• Expose new variables in application.yml (cps-application/src/main/resources/application.yml)
• Documentation of variables is to be updated (docs/deployment.rst)
