`#inspect`-ing an instance of Net::LDAP leaks auth credentials (username and password instance variables)

[astockwell]

Example:

c = Net::LDAP.new(conn_hash)
p c
=> #<Net::LDAP:0x007ffc6698a9f8 
    @host="server-001", 
    @port=636, 
    @verbose=false, 
    @auth={:method=>:simple, :username=>"cn=user,o=org", :password=>"supersecret"}, 
    @base="dc=com", 
    @force_no_page=false, 
    @encryption={:method=>:simple_tls, :tls_options=>{}}, 
    @instrumentation_service=nil, 
    @open_connection=nil, 
    @result=#<Net::LDAP::PDU:0x007ffc669895f8 
    @message_id=1, 
    @app_tag=1, 
    @ldap_controls=[], 
    @ldap_result={:resultCode=>0, :matchedDN=>"", :errorMessage=>""}>>

This can be worked around when using this gem by wrapping Net::LDAP in another class, but I don't imagine this is desirable behavior.

Could something be done similar to GitHub's octokit gem (highlighted LOC here) to mask them (or remove entirely)?

@astockwell that's a great suggestion! Would you be interested in opening up a PR with a test?

You got it 👍
