bpo-38615: Add timeout parameter for IMAP4 and IMAP4_SSL constructor (GH-17203)

Browse source 
imaplib.IMAP4 and imaplib.IMAP4_SSL now have an 
optional *timeout* parameter for their constructors.
Also, the imaplib.IMAP4.open() method now has an optional *timeout* parameter
with this change. The overridden methods of imaplib.IMAP4_SSL and
imaplib.IMAP4_stream were applied to this change.
