feat: lightPush auto retry

[weboko]

This is a feature request

Problem

It can happen that lightPush.send fail due to not having enough quality peers or peers in general.

Proposed Solutions

Enable following API:

node.lightPush.send(encoder, message, { autoRetry: true }); // retries right after peers are available with default timeout of 500ms 

node.lightPush.send(encoder, message, { autoRetry: { timeout: 1000 } ); // changes timeout to 1s

Default values:

• autoRetry - false;
• if autoRetry is true -> { timeout: 500, retries: 3 };
• in other cases should be merged with provided values;

This feature should be disabled by default as in the worst case scenario it can take some time potentially blocking consumer's app without clear reason.

timeout is to cap execution by await time
retries is to cap execution by amount of tries to .send message to peers

Notes

Original thread - #2003 (comment)

[danisharora099]

Did some optimisations on the original PR and autoRetry was necessitated as part of the functionality:

• added exponential backoff to blocking
• reduced the default initialDelay to 10ms
• reduced the default maxDelay to 100ms
• provided all options to be changed by the uses through arguments

f97c6a9 should resolve this

Looks good. Is it merged already, @danisharora099 ?
