fix(doc): Clarify documentation of Centreon clapi authentication

Added in the documentation the possibility to use the encrypted password (in base) or the password in clear

refs: #5625

Hello,

It does not seem to work like this in my case (v2.8.22):

• the statement "(MD5 by default)" fails to clarify which flavor of MD5 is used, causing malfunction when we use a different one

Impact is the encrypted password does not work as a parameter to this command, only clear text password works, which is ... bad.

MD5 has different flavors:

• linux md5
• apache md5
• php md5
  They seem to produce different passwords hashes, with different syntax:

openssl passwd -1 "totopassword"
$1$D.R/V99t$mdLKkZtXISXjhpue91cfY0
openssl passwd -apr1 "totopassword"
$apr1$ssR.ffu2$HSuvcDd1DxG2dRJJ8mK3.0

The password hash in Centreon contacts table is prefixed with "md5__" , could you clarify in the documentation what version of MD5 produces it (probably a php function) and how to re-create one from clear text password for use in the CLAPI command line (the one in teh DB does not work as is) ?

Thank you.
