Dev: ui_context: Add info when spell-corrections happen

[liangxin1300]

crmsh internally can correct some spell errors, like:

crm cluster ini   -->  crm cluster init
crm configure verfy --> crm configure verify

It will be helpful to add info when spell-corrections happen, like:

15sp2-1:~ # crm cluster ini
INFO: "ini" is accepted as "init"

15sp2-1:~ # crm configure
crm(live/15sp2-1)configure# verfy
INFO: "verfy" is accepted as "verify"
crm(live/15sp2-1)configure#
