update(timeouts): increases timeouts

[RohanSreerama5]

Updates default Wirey timeout values and also makes them configurable via the environment.

Usage notes:

The following parameters can be set via the environment. Please be sure to specify the unit, ie. seconds minutes. Values are parsed as time.Duration values.

Here's an example:

export DIAL_TIMEOUT="25s"
export TLS_HANDSHAKE_TIMEOUT="20s"
export CLIENT_TIMEOUT="1m"

All configurable parameters:

backend/http.go
DIAL_TIMEOUT
TLS_HANDSHAKE_TIMEOUT
CLIENT_TIMEOUT

backend/plumber.go
MAX_ELAPSED_TIME
MAX_INTERVAL
JITTER_RANGE

backend/etcd.go
ETCD_DIAL_TIMEOUT

What do folks think of the timeout values in the PR? I can optionally also adjust the timeouts in here

can we make that etcd value you mentioned configurable too. once completed, we would need to update the ansible wirey role to handle env vars to release this

Yup, my commit makes the ETCD_DIAL_TIMEOUT also configurable via the environment.
