bitswap/client/messagequeue: expose dontHaveTimeoutMgr configuration

[gammazero]

• Create an exported DontHaveTimeoutConfig to hold configuration values for dontHaveTimeoutMrg
• Provide function DefaultDontHaveTimeoutConfig to return a DontHaveTimeoutConfig populated with default values
• Bitswap client New has new option for caller to supply a DontHaveTimeoutConfig
• If the required onHaveTimeout function is nil, then disable the dontaHaveTimeoutMgr
• The option to disable donthavetimeout handling is respected and the dontHaveTimeoutMgr is disabled if this option is false.

This PR replaces #703

Closes #701

Thank you for removing the unused value from config, I had forgotten to do that. Everything looks good at this point, so will merge.
