Make SSH Proxy Timeout adjustable or provide at least more options than 2 minutes only

Description

By default Bamboo's SSH Proxy timeout is set to 2 minutes. This built-in Proxy is used for e.g. Git repository accesses / operations utilizing the SSH protocol.

In some cases this value is not big enough, so e.g. a git clone does not terminate in time, an error gets thrown an error and that is also logged.

This is the timeout from Bamboo's SSH client after 2 mins:

BAMBOO-SSH-PROXY: [User session has timed out idling after 120000 ms.]

Bamboo's SSH server can also timeout after 10 mins depending on the Git activity:

• BAM-21279: Increase Bamboo SSH Server timeout

Solution

Instead of requesting a patch to increase this value, if really needed, or trying to control the repository operation / the repository data in order to not exceed the 2 minute limit, Bambo could solve this unfomfortable user situation by:

• Generally making the SSH Proxy value user adjustable via Bamboo UI
• Keep the default timeout at 2 minutes (which is typically sufficient), but add the option of 5 minutes instead and additionally of 10 minutes (e.g. per radio button in Bamboo's UI)

The idea presented here is to provide a a tunability / two alternative settings globally, but could be thought further so to allow the same even on build plan level.
