Add tcp uri scheme for setting rhosts

[adfoster-r7]

Adds a tcp uri scheme for setting rhosts. This is a more generic version of the protocol specific schemas such as mysql, which also set a default port, database config etc. The tcp scheme just sets username, password, and the port if it's specified.

This will be useful for exploiting remote hosts which require a user/password/port all at once - but don't have a specific schema already defined

Verification

use auxiliary/scanner/http/title
run tcp://example.com

Looks pretty good, just had a few comments of concern to double check before this is landed.

[gwillcox-r7]

Comments resolved, will test this and land it now.

[gwillcox-r7]

Working as expected, will land this now.

Release Notes

Adds a TCP URI scheme for setting RHOSTS, which allows one to specify the username, password, and the port if it's specified as a string such as tcp://user:a b c@example.com which would translate into the username user, password a b c, and host example.com on the default port used by the module in question.
