Temporary fixes problem with command execution timeout

[dbalabka]

It temporary fixes problem that described in phpseclib/phpseclib#775.
For example composer install may be stoped on the middle of progress if it takes more than 10 sec.

@Elfet @oanhnn it will be greate to prepare new release with this fix, because this may affect many users.
I'm sure that was itroduced by #428 after phpseclib update

[antonmedv]

Ok! @deployphp/maintainer can anybody make new release?

[oanhnn]

I created a new release. @torinaki @AlexStansfield , Please test again!

Sorry I get:

PHP Notice:  Cannot connect to stage.ourserver.com:22. Error 60. Operation timed out in phar:///Users/alex/Downloads/deployer (1).phar/vendor/phpseclib/phpseclib/phpseclib/Net/SSH2.php on line 1011

When it tries to connect.

Putting in a number like 3600 does work though. I suggest putting a setting that can be changed but defaults to something reasonable like 10 minutes. PHP_INT_MAX on my machine is 9223372036854775807 and it seems it really messes with it.

@AlexStansfield , @Elfet , @oanhnn I was able to reproduce problem. Sorry guys it was my bad. Found that I was testing with patched phpseclib with few fixed issues by me.
Adding 3600 as default timeout is proper fix in this case. I have prepared PR #435 with fix and prepared functional tests that cover timeout case. Please check PR, because I have to change Travis configurations to achieve possibility to implement these tests. In case if you will not agree to change Travis changes I will remove tests from PR.

The problem was as I said before was that fsockopen do not create socket with huge timeout, but 3600 is ok for it.
