Nagios CLI commands

The commands listed below were added to be able to delete Test Servers from the Nagios configuration if needed.

There are 3 new Command Line Interface (CLI) commands available for cfguser on the TAS, listed in the TAS-help command:

##>tas-help | grep nagios

| list-nagios-ts-entries - list the Nagios TS entries |

| delete-nagios-ts-entries - delete Nagios TS entries |

| delete-nagios-all-ts-entries - delete all Nagios TS entries |

##>

From the TAS Manager console or the TAS Manager Web UI, the user has access to the delete-nagios-all-ts-entries from the System menu item via "Delete All Nagios TS Entries". This command will delete all TS profile entries, i.e. reset the Nagios's TS entries. If the user just does this, then causes the TSs to re-register (either via TAS restart, TS upgrades, or manually recycles), the Nagios will be re-initialized to display current TSs.
The TAS will now always Nagios register a TS reporting a hostname during any registration from port 8890. Before this change, the TAS would not Nagios register a TS whose hostname/IP pair has already been Nagios registered. Thus Nagios will get multiple registrations from the same TS/Hostname/IP-Address anytime the TS registers.
The TAS will automatically delete the /etc/nagios/conf.d/TS_<HOSTNAME>.cfg file, anytime a TS is deleted from the TAS. If the TS has not reported a hostname to the TAS, the TAS will use the TS's name as <HOSTNAME>. The TAS will execute this by calling the CLI, delete-nagios-ts-entries <HOSTNAME> command. The reported Hostname would be displayed in TS-Admin General tab/table.
