        Powershell installer for Cavisson Agents
    .Description
        This is a powershell installer that would install Cavisson agents on
        local and in remote servers.
    .Example
        .\install.ps1 -tier AppTier -instance Instance1 -controller controller.cavisson.com:443

        Above example installs agents to the local only
    .Example
        .\install.ps1 -tier AppTier -instance Instance1 -poolName "pool1,pool2"
            -remote user1:pass1:host1,user2:pass2:host2 -dest E:\POC

        Above example installs the agents to the remote hosts
        Password is optional and if not provided it will prompt for it but in  that case
        -remote should be in format user:host,user2:host ...

    .Example
        .\install.ps1 -appAgent 1 -machineAgent 1 -logAgent 1 -tier Apptier

	.Example
        .\install.ps1 -appAgent 1 -machineAgent 1 -logAgent 1 -silent 

	above silent option is used for installing in silent mode.


        Above examples installs machineAgent, appAgent and logAgent
	
	 .\partialuninstall.ps1 -partialuninstall 1 -machineAgent 0 -appAgent 0 -logAgent 1  
	Above example uninstall logagent partially
    .Notes
        1. When using remote option -dest is required as this script copies
           related files to the remote host. The dest path must exists and it is
           not created by the script
        2. Trusted hosts must be enabled in winrm client config
        3. Password authentication may be required for each action
