Add Remove-HFMHostsFileEntry

[Stephanevg]

Isolating discussion from #4

@LxLeChat It make sense to me to be able to remove an entry. I think we should offer the possibility to to the end user to do it in several ways:

1. via [HostsEntry] Just like in your example from Make module easier to use: Add powershell Functions  #4 It would make sense, to be able to remove an single or an array of Hostsentry objects from a given Hostsfile
2. Via String: It would be good to have have the user to write a string, which could be a FQDN or an IP address. In the background, we could handle this using a regex, and according to the type, we will fetch the corresponding entry, and if present, remove it. Perrhaps, this one should also be an array.

These are the cases I could think of

Remove-HFMHostsFileEntry -Entry  "192.168.1.34"
Remove-HFMHostsFileEntry -Entry  "Server01"

# Your example:
$a = Get-HFMHostsFile
$b = Get-HFMHostsFileContent
Remove-HFHMHostsFileEntry -Entry $b[0..5] #remove 6 first entries # Parameters should be singular.

I think this could be managed simply using a switch -Regex
where we will identify if it is IP, FQDN, netbiosName
Alos check if of Type [Entrytype]

`
#PseudoCode:

if($Entry.GetType().FullName -eq "EntryType"){
#Do work
}Else{

Switch($Entry){
     '^\d' {#Ip}
     '^\w' {fqdn or netbios}
    'default' {Throw 'not supported'}
  }

}

`

Somethig like that
