function Find-CredentialStoreItem {
<#
.SYNOPSIS
Locates a CredentialStoreItem in any CredentialStore from a given remote host item.
.DESCRIPTION
Find the credential object and return it as PSCredential object.
.PARAMETER RemoteHost
Specify the host, for which you would like to find the credentials.
.PARAMETER Identifier
Provide a custom identifier to the given remote host key. This enables you to store multiple credentials
for a single remote host entry. For example ad/sys1, ftp/sys1, sql/sys1
.PARAMETER Type
Influence in which types of CredentialStore this function will look for a object. List of possible types:
- All (include private and shared CredentialStore) - this is also the default.
- Private (only look in a private CredentialStore)
- Shared (only look in the shared CredentialStore)
.INPUTS
[None]
.OUTPUTS
