Fix TLS Proxy Timeout

[aepod]

Added timeout settings to the TLS and Varnish containers

Description

Added better defaults for timeouts on TLS and Docker.

Fixed Issues (if relevant)

1. [Cloud Docker Core] TLS Proxy Times Out after 15 Seconds #35: [Cloud Docker Core] TLS Proxy Times Out after 15 Seconds

Manual testing scenarios

Rebuild docker containers with these changes, timeouts are now 5 minutes. To test this you can use a very long running admin function, or a custom function that sleeps.

@aepod Thank you for contribution. During internal testing we found out that correct way to set timeout is:

    .first_byte_timeout = 300s;
    .between_bytes_timeout = 300s;

Without quotes and with s at the end. May you please change PR.
